"Willis McGahee was back at practice today for the Broncos, but the team's starting running back isn't a sure thing to play Thursday night against the New York Jets.

McGahee, who injured his left hamstring early in the Broncos' victory over Kansas City on Sunday, went through warm-ups and stretching but did not participate in individual drills in the portion of practice that was open to the media.

The team's only other running backs are Lance Ball, who would start if McGahee is unable to play, and Jeremiah Johnson, signed off the practice squad Monday."
