The backup outside linebacker had to leave Sunday night's win over the New England Patriots with a shoulder injury and did not return. Fellow backup linebacker Tavares Gooden has a rib injury and is also missing time, leaving the team somewhat short at linebacker. Wide receiver Mario Manningham has been out for the past two games with a shoulder injury, but he's listed as questionable for next week's game.
The Seattle Seahawks were able to get out of their meeting with the Buffalo Bills in Toronto relatively easily, but they still retain some injuries in their secondary from earlier in the year: Marcus Trufant has missed the last three weeks with a hamstring injury, and Walter Thurmond was unable to go on Sunday, also with a hamstring injury. Richard Sherman and Jeremy Lane have handled themselves just fine as the team's cornerbacks, so their return isn't of the utmost importance.
The Arizona Cardinals are fairly dinged up from past weeks, with Early Doucet highlighting a list of injured players. He missed Sunday's victory over the Detroit Lions with a concussion, and is questionable going forward. Ronald Talley, James Snyder, and Dan Williams also sat Sunday.
