Injury update

The Bills added defensive end Chris Kelsay to the injury list on Thursday when he showed up with a sore back. He was held out of practice, but will play on Sunday.

Quarterback Trent Edwards (concussion) was able to do a little bit more than he did on Wednesday, but has already been ruled out for Sunday's game.

It looks like safety Donte Whitner (ankle), tight end Shawn Nelson (migrane head ache), defensive tackle Kyle Williams (knee), fullback Corey McIntyre (knee) and right tackle Jonathan Scott (ankle) will sit out this Sunday. None of the players have practiced this week.

Cornerback Terrence McGee (knee) and safety Bryan Scott (ankle) were limited.

Meanwhile in Houston, the Texans are feeling a lot better about All-Pro wide receiver Andre Johnson (bruised lung) playing on Sunday after he went through a limited practice on Thursday. He didn't participate at all on Wednesday.

It was also good news for the Texans' defense as Pro Bowl middle linebacker DeMeco Ryans (groin) and cornerback Dunta Robinson (hamstring) practiced fully after being limited on Wednesday. The two biggest question marks among the defensive starters are rookie linebacker Brian Cushing (foot) and free safety Eugene Wilson (groin). Neither has practiced this week, though the Texans haven't ruled them out.

Cushing, a guy many people thought the Bills should have drafted instead of unproductive defensive end Aaron Maybin, leads the Texans and all NFL rookies in tackles with 56 (33 solo). Cushing was named AFC defensive player of the week after registering nine tackles, two forced fumbles, one interception and a half sack, during a Week Six win at Cincinnati.
