RENTON, Wash. (AP) — Seattle Seahawks first-round pick L.J. Collier was carted off the practice field with a right leg injury.

Collier was rushing the passer during a team session when he grabbed at his lower leg. The team didn’t offer specifics on the injury after practice Tuesday.

Collier was attended to on the field for a brief time before limping off and eventually needing a cart to get back to the locker room. Initial speculation from the scene said it appeared Collier had a high ankle sprain.

Offensive tackle Duane Brown was one of the first to get to Collier and said it, “looked like he was in a lot of pain. I’m hoping he’s all right.”

Collier was selected with the 29th overall pick in the first round of the draft in April.
