Denver has had one injured offensive lineman cleared to return, while another offensive lineman has walked away.

The Broncos activated J.D. Walton, their center who has started when healthy but has been sidelined by injuries for more than a year. They also placed guard John Moffitt on the reserve/left squad list.

The Denver Post reports that Moffitt is frustrated that he isn’t getting much playing time and is doing some soul searching. Moffitt, who was acquired in a preseason trade with the Seahawks, has been inactive for six of the Broncos’ eight games this season.

Walton was a 2010 third-round draft pick who started the first 36 games of his career before being lost for the season after the fourth game last year.
