The Cleveland Browns defense had trouble containing the Oakland Raiders offense last Sunday during a 45-42 overtime loss.
Oakland quarterback Derek Carr passed for more than 400 yards, running back Marshawn Lynch had more than 100 rushing yards, and wide Amari Cooper and tight end Jared Cook each surpassed 100 receiving yards.
But it turns out that the Browns were also battling the referees.
The NFL has admitted that the officials messed up in the fourth quarter when referee Walt Anderson blew his whistle too early when Myles Garrett and Genard Avery hit Carr, forcing a fumble that Garrett recovered.
