ENGLEWOOD, Colo. — 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.

He sat out the late afternoon session as well.

Marshall hobbled to the sideline mid-morning, 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 the morning 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. Marshall is coming off his second straight 100-catch season.

"If I had a team, I would definitely want him on it," Broncos cornerback Andre' Goodman said. "He's a big guy that runs great routes. He's a competitor — any team wants a receiver like that. We want him healthy."
