Denver Broncos quarterback Drew Lock is expected to miss two to six weeks after exiting Sunday's game against the Pittsburgh Steelers with a sprained right AC joint, according to ESPN's Adam Schefter and Jeff Legwold.
Per Mike Klis of 9News, Lock will undergo an MRI on Monday, noting that "because it's his throwing arm, team may proceed cautiously."
Lock said after the game he was "optimistic" about the nature of injury, though he noted it "felt funny" while trying to throw with the injury:
Jeff Driskel entered in relief of Lock. Driskel went 18-of-34 for 256 yards, two touchdowns and one interception in a 26-21 loss.
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.
Believing they have found their franchise quarterback, the Broncos took steps to surround him with explosive young talent. They selected Alabama wide receiver Jerry Jeudy with the 15th overall pick in the 2020 draft to complement Courtland Sutton, who had 1,112 yards last year.
Until Lock is able to return, Denver will turn to Driskel as its primary quarterback for the time being. The 27-year-old went 0-3 with four touchdowns and four interceptions in three starts for the Detroit Lions in 2019.
The Broncos (0-2) will host the Tampa Bay Buccaneers (1-1) next Sunday.
