Las Vegas Raiders backup quarterback Aidan O'Connell left the club's preseason finale against the Arizona Cardinals on Saturday night after sustaining a right wrist injury.
Following the Raiders' 10-play, 32-yard scoring drive, which resulted in a 52-yard field goal from Daniel Carlson at the start of the second quarter, O'Connell was looked at by trainers on the sideline before going into the locker room.
Raiders coach Pete Carroll said on the television broadcast that the team won't know the severity of O'Connell's injury until after the game.
O'Connell came out of the locker room later in the quarter with a cast on his right hand, while rookie Cam Miller stepped in at quarterback.
Entering his third season, O'Connell has had an inconsistent training camp. He committed four turnovers, including three interceptions, in three preseason games. O'Connell was strip-sacked in the first quarter against Arizona, even leading to a game-tying touchdown reception from Cardinals wide receiver Simi Fehoko.
