Tight end Delanie Walker is still not over his ankle injury that was suffered before the bye week. He had not practiced this week until a limited session Friday, but that should not keep him off the field on Sunday. Walker was able to play last week and actually had a productive game. It would make sense for Mike Mularkey to try to get Walker as healthy as possible by keeping him off the bum ankle.
If this was a rookie, he would probably be practicing fully to get chemistry with the team. Walker is not a rookie, though, and has shown an excellent handle of the playbook.
