For the second time in four years, the Kansas City Chiefs are Super Bowl champions.

The Chiefs, led by star quarterback Patrick Mahomes, defeated the Philadelphia Eagles 38-35 in Glendale, Arizona, on Sunday. Harrison Butker kicked a 27-yard field goal with eight seconds left to all but cinch the victory.

Things looked bleak for the Chiefs at halftime, as they trailed 24-14 and Mahomes appeared to aggravate an ankle injury. But Mahomes came back strong in the second half, and the Chiefs' offense — the best in the NFL this season — delivered down the stretch.

Mahomes, who threw for three touchdowns and 182 yards, was named the game's Most Valuable Player. He was also named the league's MVP on Thursday.
