In the second half of the game, UNLV Rebels guard Anthony Marshall tried to save a loose ball that went out of bounds underneath the basket. A New Mexico fan in the front row gave Marshall a little shove as he was walking away, but quickly realized he made a huge mistake.
Marshall stared down the fan as referees quickly stepped in to keep them separated, while the fan threw up his hands as if to say "My bad". Unfortunately, the Lobos fan had gone too far and the referees had no choice but to eject him.
New Mexico won the game 65-60.
