Carolina Panthers Player News: All Positions

News: Irvin (hamstring) didn't participate in Wednesday's practice, Joe Person of The Athletic reports.
Impact: Irvin has missed two straight games and is trending in the same direction for Week 3 versus the Cardinals. If he can't get on the practice field in some capacity by Friday, it's highly unlikely he'll be ready to play. Irvin will add a strong pass rush when he returns, but a rotation of Marquis Haynes and Brian Burns figure to slot in for the time being.
News: Allen likely will start Sunday's game at Arizona if Cam Newton (foot) is unable to play, Brendan Marks of The Charlotte Observer reports.
Impact: During last Thursday's loss to the Buccaneers, Newton aggravated the mid-foot sprain that plagued him late in the preseason. He was seen in a walking boot Monday and didn't take the practice field Wednesday, increasing concerns about his immediate availability. Allen made two appearances when Newton was absent down the stretch last season, completing 20 of 31 passes for 266 yards and two touchdowns. Assuming he gets the nod Sunday, Allen could be in line for a productive outing against a Cardinals pass defense that has given up 309.5 yards per game through two weeks.
News: Newton (foot) isn't participating in Wednesday's practice, David Newton of ESPN.com reports.
Impact: Newton is managing an aggravation of the left mid-foot sprain he's been battling since the third week of the preseason and continues to don a walking boot for extra protection. The 30-year-old would likely need to resume practicing in some capacity Thursday or Friday to have a realistic chance of suiting up Sunday versus the Cardinals. If Newton is forced to miss any time, coach Ron Rivera has said that Kyle Allen will draw the start under center.
News: Newton (foot) was still sporting a walking boot when he appeared at the Panthers' facility Wednesday morning, Ian Rapoport of NFL Network reports.
Impact: Newton presumably won't practice Wednesday, but the Panthers hope to get him back in some capacity Thursday or Friday. If not, he likely would miss Sunday's game in Arizona, with Kyle Allen then stepping in to start at quarterback. Newton is dealing with an aggravation of the mid-foot sprain he initially suffered in the third week of the preseason. He's completed 56.2 percent of passes for 6.4 yards per attempt through two weeks, adding just five carries for minus-2 yards.
News: Thompson (undisclosed) worked on the side with trainers during Tuesday's practice, David Newton of ESPN.com reports.
Impact: It's unclear what's bothering Thompson, and it likely won't be revealed until Wednesday's initial injury report. Thompson has played nearly every snap this season, making 17 tackles over the first two games, so the Panthers may just be exercising caution.
News: Short (undisclosed) worked on the side with trainers during Tuesday's practice, David Newton of ESPN.com reports.
Impact: Short didn't have an injury before this report, so the nature of it is unclear. It's a positive sign that he's still working out in some capacity, although his practice status likely will be monitored throughout the week. If he's unable to play in Sunday's game versus the Cardinals, expect Efe Obada to see an uptick in usage.
News: Allen and Will Grier both took snaps with the first-team offense at Tuesday's practice while starter Cam Newton was limited to rehab work after aggravating a left foot injury in the Week 2 loss to the Buccaneers, David Newton of ESPN.com reports.
Impact: Newton has been bothered by the foot issue since the third week of the preseason and hasn't been in top form through the first two weeks of the regular season, as evidenced in particular by his lack of involvement in the run game (five attempts for minus-2 yards). General manager Marty Hurney labeled Newton as day-to-day and was unwilling to speculate on his availability for Sunday's matchup with the Cardinals, potentially leaving Allen or Grier in line for the starting assignment. Considering Allen broke camp as the No. 2 quarterback, he would be the odds-on favorite to start if Newton is sidelined. If Allen does in fact get the nod Sunday, the Panthers would likely ask him to play the part of game manager and opt for a ground-heavy attack if the game flow allows for it.
News: Panthers general manager Marty Hurney confirmed that Newton aggravated a left foot injury in the Week 2 loss to Buccaneers, Jourdan Rodrigue of The Athletic reports. "We will see how it goes," Hurney said, when asked about Newton's availability for Sunday's matchup with the Cardinals.
Impact: Hurney labeled Newton as day-to-day, but the GM's comments cast plenty of doubt on the signal-caller's status for the weekend. Teammate Eric Reid added further fuel to that notion when he revealed that Newton was sporting a walking boot at the team facility Tuesday, per Brendan Marks of The Charlotte Observer. Newton originally sprained his left foot in the third week of the preseason, resulting in him missing the exhibition finale before he returned to deliver two underwhelming starts in the Panthers' first two regular-season contests. The 30-year-old was restricted to rehab work during Tuesday's practice and may need to turn in at least a limited showing before the end of the week for the Panthers to have any confidence in him playing Sunday. Kyle Allen, who beat out rookie Will Grier for the top backup job in training camp, would presumably be in line to start Week 3 if Newton can't go.
News: Newton aggravated a left foot injury in the Week 2 loss to the Buccaneers, leaving his status for Sunday's game against the Cardinals up in the air, Tom Pelissero and Ian Rapoport of NFL Network report.
Impact: The Panthers are expected to offer more information regarding Newton's condition at the conclusion of Tuesday's practice, which should provide more insight into the quarterback's potential to play this weekend. Newton's foot injury dates back to the third game of the preseason and may explain his uncharacteristic lack of involvement on the ground to date, as he's carried only five times for minus-2 yards through the first two weeks of the regular season. According to Max Henson of the Panthers' official site, Newton wasn't on the field for the team's practice Tuesday and was instead limited to rehab work.
