According to Charlotte Observer's Jonathan Jones, defensive end Jared Allen suffered a foot injury that likely will require surgery. He does go on to say that this is not definite but there isn't a great deal of optimism surrounding the injury.
The Carolina Panthers traded for Allen earlier this season when they placed Charles Johnson on injured reserve with a hamstring injury. The veteran pass rusher started strong with his new team with sacks in two of his first three games however he has not registerd a sack since Week 8.
There is still much unknown about the injury but according to NFL Network's Ian Rapoport Allen suffered a broken bone in his foot against the Seahawks. However, he was able to finish the game and was not on crutches after the game. Rapoport tweeted that Allen intends to continue playing.
If Allen is not able to go, the team has the mindset of "next man up" and that will be the case here. The team is deep at the position with Kony Ealy, Mario Addison and Ryan Delaire, who was inactive for today's game. Another name to watch for would be defensive end Wes Horton. He was cut earlier in the year after he served a four game suspension for violating the NFL's Performance Enhancement Drug Policy.
The Panthers brought him back and signed him to their practice squad after their final regular season game. If they hope to have him available next week they would have to create a roster space but could do so by placing Allen on injured reserve, if the injury is as serious as believed.
