Update: Arizona, ranked 11th nationally and tied for first in the Pac-12, gave USC its worst loss of the season, 74-50, last month in Tucson. The Trojans fell behind 18-4, and the Wildcats eventually led by as many as 34 points. USC reserve Ari Stewart has a broken left finger and is probably out. Backup center Omar Oraby missed practice Monday with a flu-like illness but Coach Bob Cantu said but he expects him to play.
