The Denver Broncos could get reinforcements from injured reserve this week.

After sitting out the team's last four games, rookie running back Jonah Coleman (ankle) is eligible to return against the Arizona Cardinals in Week 7. The key word is eligible, because it's not yet known if Coleman will be ready to return to action. J.K. Dobbins, RJ Harvey and Tyler Badie have handled RB duties while Coleman's been sidelined.

Meanwhile, backup offensive lineman Frank Crum (leg) and tight end Caleb Lohner (foot) are also eligible to return and have been since Week 5. Crum's timeline is uncertain. Lohner is expected to be out until at least mid-season.

Another backup lineman, Nick Gargiulo (knee), has been eligible to return from the reserve/physically unable to perform (PUP) list since Week 5. His return timeline is also unclear.
