"He sprained the ankle pretty good," Krystkowiak said. "Once you have a severely sprained ankle and you start to talk about torn ligaments, it gets pretty serious."
Lenz is out for Thursday's matchup against the Trojans. His absence creates a hole in Utah's depth chart. Lenz has started for most of the season at center.
He was one of the most improved players from last year, but has seen his minutes dwindle in the past few weeks. Krystkowiak started bringing him off the bench to be Jordan Loveridge's primary backup.
Now without Lenz the possibility exists that Princeton Onwas will play a lot more at power forward at 6-foot-5. There's a chance of junior center Marko Kovacevic seeing more minutes as well.
The awful truth
Utah spent its practice on Monday watching film and the blow-for-blow version of Sunday's awful offensive performance which yielded 46 points in 40 minutes. The Utes then did some individual workouts, but the day was dedicated to looking at the damage of Sunday.
"It was good for us," Loveridge said. "It gave us a chance to see some of the mistakes that we made and to see what we need to do to correct them."
Former Ute Jarred DuBois attended Tuesday's practice. He's currently playing in Frankfurt, Germany, in the top division in the country. DuBois played one year at Utah after transferring from Loyola Marymount. He led the Utes in scoring last season and was the catalyst for Utah advancing to the Pac-12 tournament semifinals.
Shooting guard Brandon Taylor, small forward Dakarai Tucker and point guard Delon Wright are all from Los Angeles and will all face the L.A. schools for the first time as starters.
"It will really hit me when we go back home and face them in Los Angeles," Taylor said. "Then the hometown crowd will be there and there will be the surroundings I grew up in."
