Chiefs quarterback Patrick Mahomes has been cleared from the NFL's concussion protocol and will play in Sunday's AFC championship game against the Bills, he announced Friday.
Mahomes entered concussion protocol after being injured during the Chiefs' divisional-round game against the Browns. The reigning Super Bowl champion exited the game in the third quarter with concussion-like symptoms after taking a hit.
Backup Chad Henne filled in for Mahomes and helped the Chiefs advance to the AFC title game after a key fourth-down conversion to Tyreek Hill in the team's 22-17 victory over Cleveland.
