Kansas City Chiefs head coach Andy Reid sounded optimistic about Patrick Mahomes' condition after the star quarterback sustained a concussion against the Cleveland Browns on Sunday afternoon.

Speaking with reporters postgame, following the Chiefs' victory that propelled them to the AFC Championship game, Reid explained that Mahomes had passed all the medical tests given to him following the injury.

While that does not clear the QB for next week's matchup against the Buffalo Bills, it is an encouraging sign nonetheless, per Field Yates of ESPN.

Attempting to convert a third-down play, Patrick Mahomes scampered out of the pocket before sustaining a hit to the back of the neck from linebacker Mack Wilson. Driven to the ground with his head awkwardly twisting around, Mahomes eventually required assistance leaving the field and appeared dazed as the training staff led him away. With the medical team declaring him ineligible to return shortly thereafter, the Chiefs turned to backup Chad Henne as they secured the win.

While Henne does not possess the type of physical skills that have made Mahomes an MVP, the backup was able to provide a passable impersonation of the all-world QB, at one point breaking loose for a 13-yard run that brought the Chiefs within a half-yard of sealing the game. Needing only a first down for the win, Henne took the ball out of the shotgun on 4th-&-1 and completed a pass to Tyreek Hill for the conversion and the victory.

Understandably ecstatic over the performance of Henne, the Chiefs will almost certainly require the services of Mahomes if they are to beat the Bills. Mahomes will have to clear the five-step concussion protocol handled by medical experts outside the team for him to return to the field. While there's no guarantee the quarterback will be able to do so, Reid's optimistic report has to be of some comfort to Kansas City fans.
