After making his first pre-season appearance a week ago, Buffalo Bills cornerback Terrence McGee has already been ruled out for Thursday's exhibition finale against the Detroit Lions after suffering what the team is calling a "setback" in his recovery from patella tendon surgery.

The development throws McGee's availability for Week 1 into doubt, but Chan Gailey did tell reporters on Tuesday that he did not consider McGee's spot on the 53-man roster to be in jeopardy. The Bills will cut 22 players to get to that number by 9PM Friday evening.

The news is a bit better for right tackle Erik Pears and defensive end Mark Anderson, however. Both players missed last week's game and won't play on Thursday, but Gailey told reporters that he expects both of them to be ready to play against the New York Jets in 12 days.

Oh, and in case you were dying to hear more about Tarvaris Jackson: Gailey expects the new backup quarterback to play on Thursday. To my eye, that increases the chances that the team will simply cut bait with Tyler Thigpen and roll with three quarterbacks heading into the regular season - particularly if Jackson doesn't look completely lost in Detroit.
