Jacksonville Jaguars quarterback Blaine Gabbert (left shoulder) and running back Maurice Jones-Drew (left foot) were injured in Sunday's 26-23 overtime loss to the Oakland Raiders. Jones-Drew, a Bay Area native, was injured on just his second carry of the game and took a cart ride from the sidelines to the locker room. Jones-Drew was on crutches on the sidelines during the second half. Also, cornerback Rashean Mathis tweaked his groin on Sunday.
"I don't know to what extent is, but obviously it was not well enough to play. We re-taped it numerous times and it was just too painful," Jaguars head coach Mike Mularkey said of Jones-Drew's injury according to Vito Stellino of the Florida Times-Union.
The severity of Jones-Drew and Gabbert's injuries will be determined this week.
The most costly injury, both to the team and the player, was Washington Redskins tight end Fred Davis suffering a torn Achilles, which will end his 2012 season. Playing under the one-year franchise tag worth $5.446 million in base salary, Davis leads the Redskins with 24 receptions for 325 yards and was hoping to parlay a productive season into a long-term commitment from the Redskins. With Davis suffering a season-ending injury less than a calendar year removed from a four-game suspension for violating the league's substance abuse policy, it's hard to see the Redskins committing big-time money to Davis next offseason.
According to Mark Maske, the Redskins have reached an agreement with veteran free agent Chris Cooley, who was released on Aug. 28 and will sign after passing a physical on Monday.
Redskins inside linebacker London Fletcher suffered a right hamstring that will likely require an MRI on Monday, reports Chris Russell of 980 ESPN, the Redskins' flagship station. Fletcher, 37, has played in 231 consecutive games and made 186 consecutive starts.
Cleveland Browns first-round running back Trent Richardson was "questionable" for Sunday's game with chest and rib injuries. After gaining 8 yards on eight carries in the first half, Richardson did not play in the second half after taking a hard hit when he stuffed for no gain on a third-and-1 play with 4:53 to play in the second quarter. At less than 100 percent, Richardson did not look like the player selected with the No. 3 pick in the draft, but he said that he was willing to play, but head coach Pat Shurmur held him out.
"It hurt me inside not being out there," Richardson said according to the Cleveland Plain-Dealer. "I didn't want to come out. [Coach Pat Shurmur] knows what's best, he made his decision."
Running back Ben Tate is the biggest injury concern for the Houston Texans coming out of their 43-13 win over the Baltimore Ravens on Sunday. Tate suffered a hamstring injury in the fourth quarter. For the Ravens, safety Ed Reed appeared to get hurt late in the game, but afterward said that he'll be fine with the additional time off. The Ravens are heading into their bye week.
A pair of Dallas Cowboys went down with injuries during their 19-14 win over the Carolina Panthers on Sunday. Center Phil Costa was carted off the field with a right ankle injury and appeared ticketed towards missing significant time. Head coach Jason Garrett said that Costa suffered a sprained ankle and could play next Sunday against the Giants. On defense, inside linebacker Sean Lee, the team's leading tackler, sprained the big toe on his right foot, but expects to play next week against the Giants.
"I don't think it is anything too serious," Lee said via Jon Machota of the Dallas Morning News. "I'll have to talk to the doctors and figure it out and we'll go from there."
The Minnesota Vikings have a short week to prepare for the Tampa Bay Buccaneers, who they'll face on "Thursday Night Football." The Vikings will likely be without No. 2 tight end John Carlson, who left Sunday's game with a possible concussion. Carlson has some history with concussions — he sustained a concussion in a 2010 playoff game against the Chicago Bears while with the Seattle Seahawks — and will have to go through the league's concussion protocol before he's cleared to play.
In the fourth quarter of the New York Jets' 29-26 loss to the New England Patriots, running back Shonn Greene appeared to suffer a head or neck injury, but returned to the game in overtime. Jets quarterback Mark Sanchez jammed a finger on his left (non-throwing hand) and had the digit wrapped after the game. Jets tight end Jeff Cumberland left the game after injuring his right hand that was placed in a cast. Cumberland is expected to undergo an MRI on Monday. The Patriots lost starting right guard Dan Connolly to an illness early in the game, and while they did not leave the game, tight ends Rob Gronkowski and Aaron Hernandez are clearly not 100 percent, limping their way through the last two games.
Cincinnati Bengals center Jeff Faine exited Sunday night's game against the Pittsburgh Steelers in the third quarter with a hamstring injury, pressing undrafted rookie Trevor Robinson into service. Faine is playing for Kyle Cook, who was placed on injured reserve (designated for return) in Week 1. Bengals rookie wide receiver Marvin Jones left with a knee injury while blocking on a kick return. In what could be interpreted as a bad sign, the club almost immediately ruled him out for the remainder of the game. Steelers safety Will Allen, starting in place of an injured Troy Polamalu, suffered an ankle injury in the second half and was replaced by Ryan Mundy.
