Montee Ball

Denver Broncos running back Montee Ball returned -- briefly -- to the practice field Tuesday, but the Broncos had enough concerns about their overall depth at running back to tweak the roster.

Ball, who suffered a right groin injury in the Broncos’ Oct. 5 win over the Arizona Cardinals, was in a jersey and on the practice field during the open period of practice for the first time since the injury. Ball went through the pre-practice stretching with the team and then went to work with the strength and conditioning coaches.

The Broncos have planned for Ball to miss at least three weeks with the injury -- and Thursday night’s game against the San Diego Chargers will be the third game Ball has missed -- so they promoted running back Kapri Bibbs from their practice squad, even as some teams in the league had started to circle the undrafted rookie with interest in signing him.
