The University of Arizona apologized after a portion of the team’s fanbase sang an “unacceptable chant” directed towards Brigham Young University (BYU) following the Wildcats’ men’s basketball team’s defeat at the hands of the Cougars on Saturday.

Arizona has apologized after the school says some fans participated in an “unacceptable chant” following the basketball team’s 96-95 loss to BYU on Saturday night.

The chant was just part of a tense finish in Tucson in which BYU upset the Wildcats, 96-95. The game ended with a questionable foul call on Arizona that sent BYU to the free throw line with 3.2 seconds remaining and a chance to take the lead, and Richie Saunders nailed both to seal the win.
