After practice on Wednesday, it appeared that rookie left tackle Chris Hairston was set to return to the lineup for the Buffalo Bills. Though he practiced again on Thursday, however, it's looking more likely at this point that Andy Levitre will make his third straight start on the blind side.

That after Levitre took reps exclusively at left tackle this afternoon. Bills head coach Chan Gailey told reporters after practice that the chances are better than 50-50 that the left guard will start at tackle on Sunday, giving Chad Rinehart a third straight start in Levitre's usual left guard spot, as well. Levitre will have his hands full on Sunday, as he'll draw a matchup against feared pass rusher DeMarcus Ware.

Meanwhile, rookie cornerback Aaron Williams was cleared for contact and practiced, but may still be a week away from returning to the lineup. Rian Lindell (shoulder), Demetrius Bell (shoulder) and Chris Kelsay (calf) have all but already been ruled out for Sunday's game against the Dallas Cowboys.
