Mahomes threw for 374 yards and three touchdowns in another dazzling performance, Kansas City held quarterback Lamar Jackson in check most of the rain-soaked afternoon, and the Chiefs held on for a 33-28 victory over Baltimore on Sunday.
LeSean McCoy and Darrel Williams combined for 116 yards rushing and a score in place of the injured Damien Williams, while the Chiefs (3-0) stopped the Ravens three times on 2-point attempts.
The last came after Jackson scrambled for a touchdown with 2:01 to go. The conversion would have gotten the Ravens (2-1) within a field goal, but Jackson was shoved out of bounds short of the pylon.
