Practice started with all 53 players present and working in pads Thursday afternoon, but before individual drills were over RT Bryan Bulaga was on the sideline with an apparent left knee injury.
Bulaga took part in most of the drills and didn't step off to the side until late in the part of practice open to the media. He stood on the sideline as a trainer talked with him and then removed his left knee brace.
The veteran appeared to be in some discomfort, but it's not clear whether he was able to return or was taken to the training room.
