ENGLEWOOD, Colo. -- Denver Broncos running back C.J. Anderson left Saturday morning's practice with a left shoulder injury and was being evaluated more following the workout.

But coach Gary Kubiak called it "a shoulder bang," and said Anderson wanted to return to the practice shortly after being tackled in a team drill, "but we just held him out the rest of the way."

Anderson landed somewhat awkwardly on a carry late in practice, losing the ball as he hit the ground. Trainers looked at his left shoulder, and while Anderson did not re-enter practice he kept his shoulder pads and helmet on and remained on the sideline for the remainder of the practice.

Anderson has worked as the team's No. 1 back since the start of the offseason program. Montee Ball took the majority of the carries the rest of the way Saturday with the starters.

Kubiak said Anderson will be looked at, but he didn't expect the injury to be serious.

The Broncos held out a smattering of veteran players Saturday, including cornerback Chris Harris Jr., who left Friday morning's practice with some cramping, and wide receiver Emmanuel Sanders (hamstring). Kubiak said both could have practiced, but were held out as a precaution.

"That was just me," Kubiak said. "Emmanuel could have practiced too."

Safety David Bruton Jr. (Achilles), linebacker Lerentee McCray (groin), nose tackle Marvin Austin Jr. (groin), tackle Michael Schofield (back) and defensive end Derek Wolfe (concussion) were also held out of practice.
