Neck injury may sideline Clark

LAKE FOREST, Ill. -- A swollen neck disc may prevent Chicago Bears veteran tight end Desmond Clark from suiting up Sunday night against the Eagles. Clark is a spectator once again at Thursday's practice, the third consecutive workout he has missed this week. Clark initially hurt his neck during the Arizona loss, then re-aggravated it in San Francisco, and had to exit the Niners loss early.

The veteran has always been a model of consistency, failing to play in only four games since signing with the Bears in 2003.

Clark was inactive versus Pittsburgh and Seattle because of a broken rib suffered opening night in Green Bay.

Kevin Payne (back) also appears to be skipping practice Thursday, while Pisa Tinoisamoa and Garrett Wolfe have already been officially ruled out.

Center Olin Kreutz has returned to action after missing the past two practices with a back ailment.
