Arizona Guard Trier Ruled Ineligible After Failed Drug Test

(WWJ) - The NCAA ruled Arizona men's basketball player Allonzo Trier ineligible on Thursday after results from a January drug test revealed a banned substance in his system. Arizona is appealing the decision, according to a release from the university.

Trier previously tested positive for the same performance-enhancing drug. He missed 19 games to begin the 2016-17 season until he tested negative for the substance, which has never been identified by the school. According to the school's release Thursday, the amounts of the substance were "minuscule by scientific standards" and they claim that it "appears to be a remnant" of the substance he previously tested positive for.

The junior guard is averaging 19.6 points. 3.2 assists and 3.2 rebounds per game for the 14th-ranked Wildcats. He is the second-leading scorer in the Pac-12 this season, behind freshman teammate DeAndre Ayton.
