Broncos right tackle Orlando Franklin limped off the field early during Monday's practice with an injured hip and did not return.
Coach John Fox did not specify which hip and said the severity of the injury wasn't known.
Franklin went down on the first play of team drills. While trainers attended to him, the offense and defense changed directions so they could keep practicing while Franklin was down on the field.
Franklin's injury was the latest on Denver's offensive line. After the third-year veteran went out, guard Louis Vasquez moved into his spot and recently signed Ryan Lilja moved to right guard. Manny Ramirez has been filling in at center while Chris Clark is playing left tackle in place of Ryan Clady, whose shoulder is still healing.
