The Facts: Cooper suffered a concussion in Sunday's 36-19 loss to the Los Angeles Rams, according to coach Kevin Stefanski.

Diehards Line: Cooper was injured in the second quarter while trying to catch a pass from quarterback Joe Flacco. He was taken to the locker room shortly after and ruled out with what the team called a head injury. Cooper's injury is the latest blow to a Browns offense that has been decimated by injuries. The Browns were starting their fourth quarterback this season in Flacco. Rookie Dorian Thompson-Robinson, who had started Cleveland's previous two games, is still in the concussion protocol. Cooper had 3 catches for 34 yards before the injury. Coming into the game, he led the Browns with 47 receptions for 765 yards.
