Los Angeles Rams wide receiver Brandin Cooks left Sunday's game against the Cincinnati Bengals in London due to a concussion, the team announced.
Cooks took a hard hit in the first half when he tried to make a catch down the middle of the field but he dropped the ball after getting hit in the helmet by safety Jessie Bates III. Bates was not flagged for the play.
Cooks was previously in concussion protocol after the Week 5 loss to the Seattle Seahawks but returned for Week 6 against the San Francisco 49ers.
Cooks has caught 27 passes for 402 yards and one touchdown this season.
