Pat Williams downgraded to doubtful

In a surprise move, the Vikings downgraded DT Pat Williams from questionable to doubtful with a knee injury.
According to the official injury report, that means there's a 25 percent chance he will play.
Williams has been on the injury report for weeks with the injury.
Meanwhile, CB Cedric Griffin (neck) was upgraded from questionable to probable.

For the Bears, RB Thomas Jones (groin) was removed from the injury report but DT Tommie Harris was added with a knee injury. Harris, though, is listed as probable, which means there's a virtual certainty that he will play Sunday.
