AFC West injury report

Posted by ESPN.com's Bill Williamson

Here is an injury update from Kansas City, Oakland and San Diego:

Kansas City
Linebacker Derrick Johnson did not practice with a thigh injury that knocked him out of the loss to Tampa Bay on Sunday. There appears to be a possibility Johnson does not play at San Diego on Sunday.

Safety Jarrad Page (groin) and cornerback Patrick Surtain (quad) didn't practice, either. The Chiefs signed two cornerbacks, Ricardo Colclough and David Macklin on Wednesday, so Surtain could be out a while. Punter Dustin Colquitt (groin) and cornerback Brandon Flowers (head) were practicing fully Wednesday.

Rookie running back Darren McFadden was on the practice field. He was practicing on a limited basis but after missing the past two games, it is a good sign that McFadden is, at least, getting some work in. He has turf toe injuries on both feet. Defensive end Derrick Burgess did not practice. He has missed four straight games with a triceps injury. Safety Gibril Wilson has a groin injury and he did not practice, either.

San Diego
Receiver Chris Chambers (ankle) and Antonio Cromartie (hip) both did not practice. Both players have been hampered by these injuries for several weeks. It is not a good sign that they are still being hobbled, even after the bye. This will be a situation to monitor the rest of the week.
