Arizona junior point guard Allonzo Trier is facing the second substance-induced suspension of his college career.

The university announced Thursday that Trier is indefinitely ineligible, effective immediately, per an NCAA mandate. The reason for his punishment predates the 2017-18 season. Arizona fans remember all too well that Trier sat for the first 19 games of the 2016-17 season after traces of a banned substance were found in his blood stream.

Trier became eligible last season once those traces of the undisclosed substance were no longer showing up. Oddly, according to Arizona, they have returned.
