The Kansas City Chiefs officially put four players on today's injury report for the Jacksonville Jaguars game.

Here's the roundup:

Did Not Practice

FS Jon McGraw - He has a leg strain.  Status for Sunday's game is unknown. The Chiefs are thin at free safety as it is.  Right now, McGraw is the big wildcard for Sunday.

CB Mike Richardson - Illness.  Todd Haley said he was out with the flu.

Limited Participation in Practice

C Rudy Niswanger - Reportedly sprained an MCL in the San Diego Chargers game.  His timetable isn't known either but I would say it's encouraging that he's practicing already.

Full Participation in Practice

LT Branden Albert - He's still recovering from an ankle injury but, by many accounts, should be ready to go on Sunday.
