Examining key injury situations

A look at some key injury developments in the AFC West:

It’s no surprise the Chargers put standout guard Kris Dielman on the injured reserve after he suffered a serious concussion Oct. 23 at the New York Jets.

There was initially hope Dielman would be able to return this season, but he is still dealing with issues form the concussion. Dielman suffered a grand mal seizure near the end of the team's charter flight from a game against the Jets.

One of the reason why Dielman was put on the injured reserve is he is several weeks from returning, and battered San Diego needs help. The San Diego Union Tribune reported the team signed veteran Ike Ndukwe. The Chargers signed Tony Moll on Tuesday. The newspaper reports Moll could start at Dielman’s spot Sunday because his replacement, Tyronne Green, is also dealing with an injury.

  • In Kansas City, quarterback Matt Cassel had hand surgery after being injured Sunday against Denver. Kansas City coach Todd Haley said Cassel could possibly return this season. However, a lot of it will likely depend if the Chiefs are in contention later in the season.

  • For Denver, running back Willis McGahee is listed as questionable to play Thursday night against the visiting New York Jets; McGahee has been limited in practice this week with a hamstring injury he suffered early Sunday at Kansas City. The team is hopeful McGahee can play Thursday, but it will likely be a game-time decision. The Broncos will need McGahee with backup Knowshon Moreno out for the rest of the season with a torn ACL.

  • In Oakland, running back Darren McFadden is making progress from a foot injury he suffered in Week 7. Still, he may be challenged to play at Minnesota on Sunday.
