Week 3 injury update: Could back keep Romo on sideline in St. Louis?

Wednesday’s key NFL injury updates:

The biggest name to miss practice on Wednesday was in Dallas, as Tony Romo sat out Cowboys practice with tightness in his back. The Cowboys play at St. Louis on Sunday in a matchup of 1-1 teams which rebounded from miserable season openers.

But when he met with reporters, Romo insisted the day off was more a "maintenance day," and added, "I’ll be fine. I’ll be good to go tomorrow." The injury is of particular concern as the quarterback is 34 years old and has had two back surgeries in the past two years.

In Washington, receiver DeSean Jackson did not practice, but he said he does not plan on missing an extended period of time because of his injured shoulder. In fact, he expects to play this weekend, in what is one of the biggest regular-season games of his career. "I don’t think an AC joint is jeopardizing my career in the long haul," Jackson told the media at his news conference. "If it’s all on me, I’m playing. I don’t plan on missing this game." Coach Jay Gruden said Jackson will be limited in Thursday’s practice but that he expects Jackson to play Sunday in his first game against the Eagles, his former team.

Also, tight end Jordan Reed’s hamstring kept him out of Wednesday’s practice, but there is a chance he will test the injury Thursday.

Broncos receiver Wes Welker was back at Broncos’ practice Wednesday, his first practice with the team since being reinstated following the agreement to a new drug policy. He also told media, "I feel great. I feel sharp and ready to go." Along with being out due to his PED suspension handed down in the preseason, Welker has also been recovering from a concussion suffered in an Aug. 23 preseason game — his third concussion in less than 12 months.

According to ESPN: "Under the guidelines of the league’s concussion protocol to return to play, Welker had to be cleared by an independent physician, designated by both the NFL and NFL Players Association."

For the Falcons and Bucs, Wednesday meant the final injury report before their Thursday night game. Atlanta receiver Roddy White is listed as questionable but, despite not practicing this week due to a sore hamstring, the team insists he will be ready to play, according to ESPN. "Roddy has played plenty of games in his career without practice," offensive coordinator Dirk Koetter told ESPN. "Roddy has been in this offense for seven, eight years . . . If Roddy’s healthy, if he’s able to go full-speed, he’ll play good."

Also in Atlanta, rookie left tackle Jake Matthews (sprained ankle) again practiced Wednesday and is probable and expected to play after missing last week’s loss in Cincinnati.

In Tampa Bay, three key injured Bucs took part in limited practice Wednesday: running back Doug Martin (knee) and defensive linemen Michael Johnson (ankle) and Gerald McCoy (broken hand). All three are listed as questionable. Linebacker Mason Foster and tight end Austin Seferian-Jenkins will miss the game.

On Sunday, Mark Ingram had his second strong outing in as many games this season. On Monday, it was reported the Saints running back would miss about four weeks with a broken hand. On Wednesday, the news appeared to be a little better in New Orleans.

Head coach Sean Payton told the media that Ingram did indeed have surgery to repair the displaced fracture, but added that he is optimistic the running back would not be out as long as originally feared, reportedly calling Ingram’s status more "week-to-week."

Among players who did not practice on Wednesday:

The Bengals were already holding their breath about A.J. Green (foot / toe). Now they may have a real problem on their hands with linebacker Vontaze Burfict. Both players sat Wednesday, Green no surprise as he has said he wants to test his foot on Thursday. But Burfict was also a no-go as the team now believes the stinger they thought forced him out of last week’s game against Atlanta was actually a concussion, Burfict’s second concussion in as many weeks.

49ers tight end Vernon Davis, who injured his knee and ankle against Chicago on Sunday night. Coach Jim Harbaugh said earlier in the day that the team "dodged a bullet" with respect to Davis’ injury.

Vikings linebacker Chad Greenway, who suffered a broken hand in Sunday’s loss to New England, Minnesota coach Mike Zimmer revealed Wednesday. It is not clear whether Greenway will be able to play in Week 3 at New Orleans.

Two Jets sat out, with receiver Eric Decker nursing a hamstring injury and cornerback Milliner sit out practice dealing with an ankle sprain. With the Jets playing Monday, the team said Thursday will be the heaviest practice of the week, and the Jets hope the extra day of rest allows both players to play against the Bears.

The most surprising name on the list was in Baltimore, where Joe Flacco missed practice with a cold. Flacco currently holds the seventh-longest streak in league history for consecutive starts by a quarterback, and his rare absence was rather noticeable. "It was weird," defensive tackle Haloti Ngata told ESPN. "Sizzle [Terrell Suggs] and I were thinking that we’ve never been in a practice without Joe Flacco being out there."

Among players who did practice Wednesday:

Vikings tight end Kyle Rudolph, who showed up on the team’s injury list Wednesday with an abdominal injury and practiced on a limited basis.

Browns tight end Jordan Cameron (shoulder) and linebacker Barkevious Mingo (shoulder) both returned to practice on a limited basis, but both are still far from locks to play this weekend against the Ravens. Coach Mike Pettine told reporters running back Ben Tate (knee), who did miss practice, is not expected to be ready to play.
