To make room on the roster for Prentice, the Broncos placed offensive lineman Nick Gargiulo on injured reserve. Gargiulo was carted off the field on Saturday night with what appeared to be a devastating knee injury, which will end his season. It's a tough blow for Gargiulo, who was trending towards being on the 53-man roster.

Earlier today, Denver Broncos insider Mike Klis reported the Broncos had signed fullback Adam Prentice. In order to make room for Prentice, a corresponding roster move had to be made. According to Zac Stevens of DNVR, offensive lineman Nick Gargiulo has been placed on injured reserve. That news was confirmed by Chris Tomasson of the Denver Gazette.

Behind Gargiulo, the Broncos have center Alex Forsyth, an undrafted rookie pair in Xavier Truss and Clay Webb, and a pair of journeyman veterans in Will Sherman and Calvin Throckmorton. We'll find out soon what the specific severity of Gargiulo's injury is.
