If Kansas City is going to advance to the AFC Championship, the Chiefs will have to do so without Patrick Mahomes.
The superstar signal-caller was ruled out of Sunday's game against the Cleveland Browns after previously being evaluated for a concussion.
The former league MVP left the AFC Divisional Round game with 7:44 remaining in the third quarter after a hard hit by Cleveland's Mack Wilson.
At the time of Mahomes' exit, the Chiefs possessed a 19-10 lead.
Backup signal-caller Chad Henne replaced Mahomes and led Kansas City to a field goal six plays later. It extended Kansas City's lead to 22-10, which was the advantage the Chiefs took into the fourth quarter.
The Browns closed the gap to 22-17 when the official word came about Mahomes being ruled out.
