Los Angeles Rams wide receiver Brandin Cooks suffered a concussion Sunday versus the Cincinnati Bengals and was ruled out at the end of the first quarter.
Cooks had already sustained one documented concussion earlier this season, and he's dealt with others in the past.
The speedy pass-catcher entered Week 8 with 27 receptions for 402 yards and one touchdown. He's put together four consecutive campaigns with at least 1,000 receiving yards.
