PITTSBURGH (AP) — The Denver Broncos may have to dig themselves out of an 0-2 hole without quarterback Drew Lock. Lock exited a 26-21 loss to the Pittsburgh Steelers with a right shoulder injury. The second-year starter was running to his right when he was hit hard by Pittsburgh linebacker Bud Dupree. Dupree drove Lock's throwing shoulder into the ground. He fumbled on the play then went to the medical tent to get evaluated and did not return. Jeff Driskel threw for 256 yards and two touchdowns in place of Lock despite absorbing six sacks. The Broncos host Tampa Bay next week.
