C.J. Stroud suffered a concussion in Week 9 against the Denver Broncos in 2025. He left the game in the second quarter after a hit while sliding and was ruled out for the remainder of the game, subsequently entering the league concussion protocol. This marked his second documented concussion, with a previous one noted in December 2023 against the Jets. Stroud's return date would depend on medical clearance following protocol and team decisions.
