The Cardinals placed Minshew (elbow) on injured reserve Tuesday, Darren Urban of the team's official site reports.
While the Cardinals have yet to confirm that Minshew sustained a torn UCL in his throwing elbow during Sunday's loss to the Seahawks, Adam Schefter of ESPN relays that the veteran signal-caller is unlikely to play again this season. With Minshew out of commission, rookie third-round pick Carson Beck will step in as the Cardinals' new starting quarterback beginning with Sunday's game against the Rams. Across two appearances (one start) with Arizona before sustaining the elbow injury, Minshew completed 38 of 53 passes for 354 yards, three touchdowns and no interceptions while adding four yards on his lone carry.
