Las Vegas Raiders quarterback Aidan O’Connell was carted to the locker room with an air cast on his left leg after being pushed from behind by Tampa Bay Buccaneers defensive lineman Calijah Kancey in the third quarter on Sunday.

The Raiders soon ruled O’Connell out for the rest of the game with a knee injury.

O’Connell was fleeing pressure toward the right sideline with 1:23 left in the quarter when Kancey shoved him from behind after the play. No penalty was called.

O’Connell began the season as a backup but became the starter after Gardner Minshew suffered a broken collarbone on Nov. 24.

O’Connell, who was 11-for-19 for 104 yards and an interception, was replaced by Desmond Ridder.

The 26-year-old entered the day with a 64.1 completion percentage for 795 yards, four touchdowns and two interceptions over his first five games (three starts) of his second NFL campaign.
