Well this is not really what anyone wanted to see. Kenny Britt finally agreed to a contract yesterday but still didn't practice on Sunday because of an injury. The Tennessean article does not mention what the injury is. He was placed on the physically unable to perform list. Players can be taken off this list at the team's discretion according to Jim Wyatt.
It is frustrating to see this to say the least. The Titans finally draft a receiver in the first round, and he can't get himself on the field at all on the first weekend of training camp. We all know how hard it is for rookies to get on the field under Jeff Fisher, and it becomes more and more unlikely that he will get on the field with each practice he misses.
