Bush participated in drills during the open portion of practice. That he was out there and moving around fairly well bodes well for his chances to play Sunday.
In another good sign, defensive tackle Nick Fairley practiced for the third straight day.
Right tackle Jason Fox (groin), wide receiver Patrick Edwards (ankle) and safety Louis Delmas (knee) were not at practice Friday. Defensive end Jason Jones (knee) was there but didn't have his helmet, so he wasn't practicing.
Jones and Delmas missing Friday practices is the norm. Fox and Edwards have not practiced all week, and Edwards told me Thursday he wasn't sure if he was going to be playing Sunday.
