Disgruntled Denver Broncos wide receiver Brandon Marshall missed the last hour of practice Sunday after pulling up with an apparent hamstring injury while running a deep sideline route.
Marshall hobbled to the sideline, tossed his helmet and dropped to the grass. He didn't return to action, staying on the sideline a few minutes before limping to the trainer's room.
Coach Josh McDaniels said after practice that he wasn't sure how bad Marshall was hurt.
Marshall has had another drama-filled offseason, this time complaining about his contract and requesting a trade four months after appearing in his first Pro Bowl.
He has made several spectacular plays at camp so far, showing no ill effects from offseason hip surgery.
