Tampa Bay Buccaneers quarterback Jameis Winston has left the Bucs' game against the Arizona Cardinals with a shoulder injury.

After the offense left the field, Winston was seen tossing the ball on the sideline to try to loosen his arm up, and he briefly returned to action. Based on sideline shots, it seemed like Winston was upset he wasn't able to continue to play.
