Leber a spectator

Strongside linebacker Ben Leber, listed as questionable with a sprained left knee, did not participate in the first part of practice on Thursday. Leber's chances of playing Sunday truly do look questionable, which means there's a 50-50 chance he'll play. If that's the case, then Dontarrious Thomas likely would start in Leber's place. Defensive tackle Kevin Williams, who was tending to personal matters Wednesday, returned to practice.
