'Clay/ Glenn injury updates: Left tackle Cordy Glenn has been significantly limited during the early parts of camp. Glenn said on one of the first days that he felt fine, but apparently that's not the case. Glenn missed Thursday's session and head coach Sean McDermott expressed his concern for Glenn and his ankle injury. Charles Clay also had a rest day, his second of camp. McDermott appeared to be less concerned about his tight end, but it's still noteworthy that Clay has had two days off in a week's worth of practices. Also missing practice were Ian Seau, Greg Mabin, Colt Anderson, and Micah Hyde as a precautionary measure after he hit the ground hard on Wednesday.'
