The NCAA has ruled star Arizona guard Allonzo Trier ineligible effectively immediately due to a second positive performance-enhancing drug test. The university plans to appeal the decision, as they believe the test was positive because Trier unknowingly ingested a substance in 2016.
"In late January 2018, Allonzzo participated in an NCAA student-athlete drug screening," Arizona's athletic department said in a statement. "The results of that test, confirmed today, revealed the reappearance of a trace amount of a banned substance.
"The amount detected was miniscule by scientific standards and appears to be a remnant of a substance, which the NCAA agreed, Allonzo had unknowingly ingested in 2016.
