Boston Celtics Player News: Centers

News: Williams recorded 16 points (7-9 FG, 2-3 FT), 16 rebounds, four assists and a blocked shot across 21 minutes during Thursday's 113 -87 win over the Grizzlies in the Las Vegas Summer League.
Impact: As the Celtics roared to 4-0 in this blowout win, Williams kept rolling as well. The 21-year old showed some toughness by playing through a hip bruise, which should impress the Celtics brass as they attempt to construct a frontcourt lineup without Al Horford and Aron Baynes. Enes Kanter will be the likely starter this year, but Williams is making a case for a spot on the bench come October.
News: Williams won't play in Tuesday's summer league game due to a right hip bruise.
Impact: Williams had nine points and nine rebounds in Saturday's contest, so it appears to be a recent injury. It's unclear when the 21-year-old is expected to return to the court.
News: Williams posted nine points (4-9 FG, 1-2 FT), nine rebounds, three steals, two assists, and two blocks in 19 minutes during Saturday's 96-82 win over the 76ers.
Impact: Williams put together a solid showing and stat line, pitching in across every category while doing work on the defensive end. While the Celtics essentially swapped Al Horford and Aron Baynes for Enes Kanter this offseason, Williams will nevertheless need to prove himself to coach Brad Stevens.
News: Poirier agreed to a two-year contract with the Celtics on Tuesday, Shams Charania of The Athletic reports.
Impact: Poirier is coming off a pair of seasons with Baskonia in Spain and is a traditional big man at 7-feet. He averaged 9.1 points and 6.2 rebounds per game in 2018-19 and could provide Boston with some much-needed size and depth in the frontcourt should he make the final roster.
News: Kanter and the Celtics agreed to terms Monday on a two-year, $10 million contract, Shams Charania of The Athletic reports.
Impact: Kanter waited out the initial rush of signings and will now head to Boston, where he'll join a Celtics team rebuilding on the fly following the departures of Al Horford and Kyrie Irving. Kanter is far from a Horford-caliber defender, but he'll bring scoring and rebounding to the frontcourt and could be in position to open the season as the starter. Splitting last season between the Knicks and Blazers, Kanter finished with combined averages of 13.7 points, 9.8 rebounds and 1.7 assists per game.
News: Horford, despite prior reports that he was likely to stay with the Celtics, is expected to sign a four-year contract elsewhere, Steven Bulpett of the Boston Herald reports.
Impact: In a same-day change of plans, it appears Horford will be moving on from Boston. This is a significant hit for the Celtics, as he's been a cornerstone of the franchise since 2016-17. The Celtics were reportedly ready to offer Horford a three-year deal, but another team has apparently arrived with a four-year offer that could be hard for the 33-year-old to turn down.
News: Horford will not exercise his player option for the 2019-20 season but wants to sign a new deal with the Celtics this offseason, Adrian Wojnarowski of ESPN reports.
Impact: Horford will officially be an unrestricted free agent after turning down his $30.1 million option, but unsurprisingly, the big man wants to remain with the Celtics. Chances are Horford is going to sign a more affordable long-term deal with the Celtics at some point in July after free agency begins, but big money offers from other teams could potentially change things for the free agent.
News: Baynes exercised his $5.9 million player option for 2019-20 Wednesday, Shams Charania of The Athletic reports.
Impact: Baynes has played a meaningful role as Boston's reserve center over the past two seasons. He's appeared in 132 regular-season and 28 playoff games with the Celtics, averaging 5.8 points, 5.1 rebounds and 1.1 assists across 17.5 minutes in regular-season action.
News: Celtics' executive Danny Ainge said Wednesday that Horford's future in Boston will be a priority this offseason, Jay King of The Athletic reports.
Impact: The 33-year-old holds a player option for more than $30 million next season, but Ainge intimated that the team may look to work with Horford on restructuring the deal. That would likely mean tacking on some additional years, while lowering Horford cap hit for the 2019-20 season. At this point, it's unclear if Horford will be receptive to such an agreement, but given his age, it's a solution that could benefit both sides.
News: Horford finished with nine points (4-13 FG, 1-5 3Pt), seven rebounds, six assists and a steal over 36 minutes in the Celtics' loss to the Bucks on Wednesday.
Impact: Horford finished with just nine points in Wednesday's loss, struggling to hit shots from the field. He contributed with solid rebounding and assist totals, but his lack of scoring was most noticeable. The Celtics as a team shot just 31.2 percent from the floor and 17.9 percent from deep en route to getting blown out by 25 points.
News: Baynes will start Wednesday's Game 5 against the Celtics, Mark Murphy of the Boston Herald reports.
Impact: Baynes will start for the first time in the Celtics' second-round series. Compared to the first-round series against Indiana in which he averaged 19.3 minutes, Baynes' seen his workload decrease to a mere 7.0 minutes per game in four contests with the Bucks. With the Celtics facing elimination, Baynes could be in line for a heavy workload if he can manage to hinder some of Milwaukee's offensive salvo.
News: Horford totaled 20 points (8-16 FG, 3-8 3Pt, 1-1 FT), six rebounds, five assists and a block over 38 minutes in the Celtics' loss to the Bucks on Monday.
Impact: Horford was at it once again on Monday, producing a well-rounded stat line with contributions across multiple categories. Horford has done his part for the Celtics with his work on both ends of the floor, yet Boston has lacked any dominant playmakers who can go toe-to-toe with Giannis Antetokounmpo. With Kyrie Irving and Jayson Tatum struggling in this series, Milwaukee has stormed back from an 0-1 deficit to lead the series 3-1.
News: Horford totaled 15 points (6-10 FG, 3-5 3Pt), eight rebounds and three assists over 29 minutes in the Celtics' loss to the Bucks on Tuesday.
Impact: Horford had a great line on Tuesday, though he noticeably regressed after a huge Game 1 performance. Horford's five turnovers were uncharacteristic of the steady and efficient big man. Milwaukee unsurprisingly came out aggressive and urgent after dropping Game 1 at home, and Boston was simply outplayed and outhustled. Horford and the Celtics will have a chance to retake the series lead on Friday when the matchup comes to Boston.
News: Baynes (ankle) is available for Tuesday's Game 2 against Milwaukee.
Impact: Baynes suffered a sprained left ankle in Game 1, but he'll play through it during Game 2. In the series opener, he posted four points and one steal in nine minutes.
News: Head coach Brad Stevens said he expects Baynes (ankle) to play in Tuesday's Game 2 against the Bucks, Jay King of The Athletic reports.
Impact: Baynes suffered the left ankle sprain in Game 1 and ended up playing just nine minutes in the victory. However, it looks like Baynes should be good to go for the series' second outing, but it wouldn't be surprising if he was limited again should he be available.
News: Baynes is considered questionable for Tuesday's Game 2 against the Bucks due to a left ankle sprain.
Impact: Baynes limped off the court in Game 1 after turning his ankle, and his status for the second matchup of the series is in jeopardy at this point. The Celtics should have a better idea on the big man's status closer to tipoff. Marcus Morris would see a heavier workload if Baynes can't go.
News: Baynes banged out four points (1-1 FG, 1-1 3Pt, 1-2 FT) and one steal across nine minutes in Sunday's 112-90 Game 1 road win over the Bucks.
Impact: Baynes, who again tweaked his left ankle, played a minor role during Boston's surprising Game 1 road win. Coach Brad Stevens preferred to go small, starting Marcus Morris at the power forward spot. In post-game interviews, Baynes claimed he was ready to go back into Game 1 despite the ankle injury, per A. Sherrod Blakely of NBC Sports Boston. Stevens has kept his lineups close to the vest during the playoffs, though one would expect to again see Morris get the start Tuesday based on Sunday's success.
News: Horford finished with 20 points (8-16 FG, 3-5 3Pt, 1-2 FT), 11 rebounds, three assists, three blocks and a steal across 32 minutes in the Celtics' win over the Bucks on Sunday.
Impact: Horford put together a massive effort in Sunday's blowout win, doing work on both ends of the court. He scored an efficient 20 points and pulled down 11 boards while swatting three shots. His defense on Giannis Antetokounmpo was probably his most important contribution, and Boston sits pretty with a 1-0 series lead with an impressive road win.
News: Baynes did not return to Sunday's game in Milwaukee as a precaution after rolling his left ankle, Jared Weiss of The Athletic reports.
Impact: Between the Celtics holding a big lead in the fourth quarter and the history of Baynes rolling his left ankle this year, head coach Brad Stevens decided to not put him back on the floor to avoid risking another injury. He'll be evaluated Monday to make sure nothing gets worse overnight, but he was cleared by trainers to return Sunday and should be considered probable to play Tuesday. Prior to leaving Sunday's contest, Baynes had scored four points (1-1 FG, 1-1 3PT, 1-2 FT) with one steal in nine minutes.
News: Baynes (ankle) has been cleared to return to Sunday's matchup with the Bucks.
Impact: Boston diagnosed their center with just a rolled left ankle after he fell to the floor in the third quarter. He'll be available to return to the game and there shouldn't be any concern that the injury will have a long-lasting effect unless he were to aggravate it again.
News: Baynes went to the locker room in the third quarter Sunday against the Bucks with an apparent ankle injury, Jay King of The Athletic reports.
Impact: The Celtics' center took a spill to the floor, and after staying down for a while he was able to walk off the court under his own power and go straight to the locker room. He's questionable to return to the matchup, although Boston would have a tough time replacing him if he needs to miss an extended time period.
News: Baynes had just two points, two rebounds, and one steal in 18 minutes during Sunday's 110-106 victory over Indiana.
Impact: Baynes did very little to trouble the scorers Sunday, ending the victory with just two points in 18 minutes. He is basically out there as a big body to match up with the size of Indiana and barely features in their offensive structures.
News: Horford totaled 14 points (4-19 FG, 1-6 3Pt, 5-6 FT), 12 rebounds, and five assists in 33 minutes during Sunday's 110-106 victory over the Pacers.
Impact: Horford ended with a double-double Sunday, thankfully saving what was a terrible shooting night. He hit just 4-of-19 from the floor and failed to pick up a defensive stat. The Celtics are now through to the second round of the playoffs where they will likely face the Bucks who are just one victory away from also recording a first-round sweep.
News: Horford had 16 points (6-12 FG, 3-6 3Pt, 1-2 FT), eight rebounds, four assists, one steal, and one block in 36 minutes during Friday's 104-96 victory over Indiana.
Impact: Horford played 36 minutes in Friday's Game 3 victory, showing no lasting effects from an apparent illness that had been hanging around earlier in the week. Horford managed to contribute across the board whilst also holding Myles Turner and Domantas Sabonis to a combined 25 points. Boston will be hoping for a repeat performance Sunday with a victory moving them onto the second round where they would await the winner of the Toronto and Orlando series.
