TUCSON, AZ (3TV/CBS 5) -

Arizona guard Allonzo Trier has been declared ineligible by the NCAA after testing positive for a banned substance, the university said Thursday.

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 minuscule 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.

Arizona is appealing the ruling.

Trier will not be in the lineup Thursday when the Wildcats face Oregon State. 

The 14th-ranked Wildcats (21-6, 11-3) have four regular-season games left before the Pac-12 Tournament starts March 7 in Las Vegas.

Trier sat out the first 19 games in 2016-17 after testing positive for the drug. He won an appeal with the NCAA and was allowed to return after the substance cleared his system.

"I have never knowingly taken a banned substance," Trier said in a statement last season. "After finding out that I was given a banned substance by a well-intentioned, but misguided person not associated with the University after an injury, I presented this information to the NCAA. The NCAA agreed that I had no knowledge of receiving the substance and my eligibility was restored."

Trier has been a key cog in the Wildcats' bid to win their fourth Pac-12 title in five seasons. He is second to freshman Deandre Ayton for the team scoring lead at 19.6 points per game and second with 3.2 assists.
