ORCHARD PARK, N.Y. — Melvin Gordon matched a career high by scoring three touchdowns, and the Los Angeles Chargers defeated Buffalo 31-20 in manhandling the anemic Bills during rookie quarterback Josh Allen‘s debut as a starter. Gordon scored on a 20-yard run and added two touchdowns receiving before limping off the field after appearing to hurt his left leg early in the fourth quarter. The Chargers did not have an update on Gordon’s status after he was evaluated in a tent on the sideline. Gordon finished with just 28 yards rushing and six catches for 38 yards in his second three-TD game.
