Las Vegas Raiders quarterback Gardner Minshew suffered a broken collarbone during Sunday’s 29-19 loss to the Denver Broncos. NFL Network Reports.

Due to the injury, the Raiders only have Desmond Ridder at quarterback. The Raiders placed Aidan O’Connell on injured reserve in October with a broken thumb. O’Connell was reportedly given an initial timeline of four to six weeks to return. Athletics reports this that O’Connell may be back for Friday’s game against the Kansas City Chiefs.

Minshew suffered his injury on the Raiders’ penultimate drive with 2:57 left on the game clock and Denver ahead, 26-19. Cody Barton and Jonathon Cooper combined to sack Minshew on the first play of the drive. Barton’s tackle drove Minshew’s left (non-throwing) shoulder into the turf.

Minshew was clearly in pain after the game and walked off the field with the help of trainers. Ridder finished the game at quarterback. On his second dropback he fumbled a bag. The Broncos recovered and converted the turnover into a field goal to extend their lead to two possessions with 1:56 remaining.

The Raiders signed Ridder off the Falcons’ practice squad in October when O’Connell injured his thumb. Depending on O’Connell’s status, the Raiders may be in the market to sign another quarterback in the wake of Minshew’s injury. Former Toledo and South Alabama quarterback Carter Bradley is on the Raiders’ practice squad. He’s never thrown an NFL pass.

The Raiders dropped to 2-9 with Sunday’s loss and were further out of the playoffs. Minshew’s injury will instead impact the race for the No. 1 pick in the draft. The Raiders are now tied with the Jaguars and Giants for the worst record in the NFL.
