‘The Bills could be doing some juggling at tight end against San Diego if Scott Chandler can’t play or is less than 100 percent. Chandler, who is having one of the best seasons by a Buffalo tight end in years with 35 catches for 360 yards and six TDs, injured his ankle in last week’s loss to Tennessee. He did not practice Wednesday and the team is holding out some hope that he’ll get on the field Thursday. The plan if Chandler can’t play is to use rookie Lee Smith and Mike Caussin in a rotation. Coach Chan Gailey said it would basically take Smith and Caussin to replace what Chandler does.’
