As expected, the Broncos have placed center J.D. Walton on injured reserve with a fractured/dislocated ankle.
Taking his place on the active roster will be linebacker Joe Mays, who returns after serving a one-game suspension for his Week 3 hit on Texans QB Matt Schaub.
Tight end Virgil Green, who is back working with the team after serving a four-game PED-use suspension, was also reinstated to the active roster.
To make room for him, Mike Mohamed was waived. Should he clear waivers, the linebacker would figure to end up back on Denver's practice squad.
Walton, who was playing in his third season after being drafted by Denver out of Baylor, joins fellow ex-Bear lineman Philip Blake on IR, along with DE Jeremy Beal, S Quinton Carter, RB Mario Fannin, DE Jason Hunter, and DT Ty Warren.
