‘Rapp’s knee appeared on the injury report for the first time since training camp Wednesday and he didn’t practice all week. McDermott said the injury has been bothering him since training camp, when he was in and out of practice for a week. After becoming a mainstay in the starting lineup last year, Rapp’s third season with the Bills has been rocky. Rapp missed seven tackles in the first six games as Buffalo’s secondary had seven pass break-ups, two interceptions and 17 missed tackles.’
