During Tuesday’s morning practice, guard Chris Kuper suffered a left forearm fracture. He is expected to fully recover within four to six weeks.
Kuper was in the process of returning to the lineup after recovering from an injury suffered in Week 17 of the 2011 season. As he worked his way back to the first unit, he often split reps at right guard with Manny Ramirez, a sixth-year lineman who has started 15 of his 20 NFL games played.
If Kuper returns in four weeks, he would presumably be part of the team’s preparation for its Week 2, Monday Night Football matchup in Atlanta. Six weeks from today is Sept. 25, leading up to the Broncos’ Week 4 home game against the Oakland Raiders.
Kuper was one of three players who left Tuesday’s practice early, along with running back Ronnie Hillman (hamstring) and defensive end Jason Hunter (triceps).
In addition, safety Jim Leonhard (knee), safety Quinton Carter (hamstring and knee), linebacker Keith Brooking (hamstring), cornerback Tracy Porter (illness), linebacker Danny Trevathan (ankle) and wide receiver Tyler Grisham (knee) did not participate in Tuesday’s practice. Defensive tackle Ty Warren was excused for “a family situation.”
“You’re concerned about all of them — you’d like them out there because this is how we get better,” Fox said of the injured players before the severity of Kuper’s injury was announced. “But we take a next-man-up approach, and it gives the guys behind them an opportunity.”
