Ryan Succop nailed a 54-yard field goal for the lone points of the first quarter and Cairo Santos' 44-yarder in the second gave KC a 6-0 lead before Stewart rushed in for scores of two and three yards, respectively, to give Carolina a 14-6 advantage going into the break.
A 25-yard Succop field goal and Kelce's 43-yard TD catch staked the Chiefs to a 16-14 third-quarter edge, but the Panthers posted two more touchdowns to close the frame.
