Patrick Mahomes and DeAndre Washington were once college teammates, but now that they're in the NFL, they are bitter divisional rivals.

The former Red Raiders still showed love after their first game against each other by trading jerseys after the game as a sign of respect.

Washington scored a touchdown in the game, and another former Red Raider, Michael Crabtree, caught the game-winning touchdown pass with no time left on the clock.

The Chiefs and the Raiders play again Sunday, December 10.
