Carr has faced the most fearsome pass rushers, toughest cover cornerbacks and most accomplished defensive schemers throughout the season with the Oakland Raiders. The task doesn't get any easier this week when the Raiders (2-12) host the Buffalo Bills (8-6), who shut down Green Bay's potent offense last week and did not allow a touchdown pass in consecutive games against Peyton Manning and Aaron Rodgers. The two star quarterbacks combined to complete 31 of 62 passes for 358 yards, no touchdowns and four interceptions the past two weeks. "The fact that I don't know what's going to happen, that's hard, but right now I'm focused on playing my heart out for (Sparano)," Carr said. Because I love him, I love him to death, love playing for him. RT Menelik Watson (foot, ankle), CB Tarell Brown (foot), CB Chimdi Ckekwa (hamstring), DL C.J.
