The Denver Post reports that the Broncos are not putting Warren on season- ending injured reserve. Recovery time for torn triceps is three to six months.
Warren, who signed with the team earlier this month after being released by New England, suffered the injury during Monday's practice.
The 30-year-old Warren missed all of last season with a hip injury suffered during the preseason. He had been with New England since 2003, and was a full-time starter since '04.
