Kerr Kriisa will not play in Arizona’s semifinal game against Colorado.

That felt like the likely outcome after the Arizona guard came down on a teammate’s foot and turned his right ankle late Thursday in UA’s win over Stanford. Kriisa posted to social media after the game with a picture of his foot in a boot and his butt planted in a wheelchair. On Friday, he arrived at T-Mobile Arena on crutches, putting little weight on his right foot.

CBS Sports’ Seth Davis reported Friday that Arizona is hopeful Kriisa can return next week for what the Wildcats hope is a lengthy stay at the NCAA Tournament and that early returns on the severity of the sprain were “promising.”

Kriisa is averaging 10 points and five assists for the Wildcats this season. He’s the initiator for one of college basketball’s most efficient offenses and a timely shot-maker.

Sixth-year senior guard Justin Kier will start Friday’s game against the Buffs in Kriisa’s place. Kier finished out the Stanford game after Kriisa’s injury and delivered the pass to Christian Koloko for the de-facto game-winning bucket. Against Colorado, the Cats will need him to be sharp.
