re: Big Ed Alexander injury?

He participated in the scrimmage Saturday. I’ve read he has an old knee injury that flares up occasionally so they manage it with intermittent rest. Supposedly his weight is good they’re just trying to keep it that way and keep tread on the tires so he can rotate situationally during the season. Aranda doesn’t play a NT on every down so the goal is to have him ready to go when called on.
