Gibson (shin) doesn't have an injury designation for Sunday's game in Denver, John Keim of ESPN.com reports.
Gibson will continue playing through his stress fracture and figures to continue dominating Washington's rushing volume, but he has lost a few more snaps to pass-catching specialist J.D. McKissic in recent weeks, in part because Washington regularly has been chasing deficits. While the shin injury also may be a factor, Gibson still has 12 or more touches in every game this season.
