‘Another starter, defensive tackle Jermaine Haley, said he is considering undergoing surgery on his injured thumb. The procedure would sideline him three to four weeks, he said. The Redskins also will be without cornerback Fred Smoot, who has a fractured sternum, and almost certainly will be without tailback Trung Canidate for Sunday’s game at Buffalo. But with a bye week after the Bills game, club officials hope both will be able to play Nov. 2 at Dallas.’
