Los Angeles Chargers wide receiver Keenan Allen, left, can't make the catch as Kansas City Chiefs cornerback Charvarius Ward, right, defends, during the second half of an NFL football game Monday, Nov. 18, 2019, in Mexico City.
The Chiefs held Los Angeles to eight points in the second half, and Sorensen grabbed Rivers underthrown pass to Austin Ekeler at the goal line to secure the Chiefs 10th win over Los Angeles in 11 meetings.
The game was particularly special to Chargers cornerback Michael Davis, the son of a U.S. immigrant from Mexico City.
But the Chargers trailed 10-9 at halftime despite outgaining Kansas City 312-109 and making five drives into Chiefs territory.
After Williams scored on the Chiefs opening drive of the second half, Mahomes hit Kelce with a picture-perfect 23-yard TD throw on the next drive.
