The Kansas City Chiefs Thursday injury report is identical to Wednesday's with S Jon McGraw and C Casey Wiegmann as the only two players listed.
McGraw has a high ankle sprain which cost him last week's game and the early indications are that it will likely cost him Saturday's game against the Oakland Raiders as well. He was limited on Thursday. Clearly, the Chiefs can operate well in the secondary without McGraw as evidenced by last week's game against Green Bay (it's just a matter of doing it consistently).
Wiegmann has a calf injury and was limited for the second consecutive day. No word on his status for Saturday at this point.
The Raiders injury report isn't out yet -- damn West Coast time -- so we'll update that later but the early reports say RB Darren McFadden is unlikely to play.
