Denver Broncos quarterback Drew Lock exited Sunday's game against the Pittsburgh Steelers after suffering an apparent shoulder injury.
Jeff Driskel came in the game after Lock left the game.
Expectations are high for Lock this season after his promising finish in 2019. The Missouri alum threw for 1,020 yards, seven touchdowns, three interceptions and completed 64.1 percent of his attempts in five starts as a rookie.
The Broncos went 4-1 with Lock under center after going a combined 3-8 with Joe Flacco and Brandon Allen as their starting quarterbacks.
