KANSAS CITY, Mo. (AP) — Kansas City Chiefs quarterback Patrick Mahomes was being evaluated for a concussion Sunday after leaving their divisional-playoff game against the Cleveland Browns with 7:27 left in the third quarter. Mahomes tucked the ball on a quarterback option and tried to reach the first-down marker on third-and-1 near midfield when he was brought down hard by Browns linebacker Mack Wilson, who had managed to get ahold of him around his helmet.
