Star Arizona guard Allonzo Trier has been declared ineligible by the NCAA after testing positive for a banned substance, the university said Thursday.
Arizona is appealing the ruling.
According to the school, Trier was tested in late January, and the results "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," Arizona said in a statement.
Trier is averaging 19.6 points for No.
