The Arizona-Colorado game originally scheduled to be played Wednesday has been moved to Dec. 28 at McKale Center.
The Buffaloes were forced to pull out of what would have been the Pac-12 opener for both teams Wednesday because two positive tests and related contact-tracing left them short enough players.
Arizona's Pac-12 opener is now scheduled to be at Stanford on Dec. 19, but that game will be postponed or moved to a site that is not yet determined because of a Santa Clara County health order prohibiting practices and games until at least Dec. 21.
The Cardinal remained in North Carolina after finishing play in the Maui Invitational this week and is attempting to find nonconference games in that area this month.
So far, none of Arizona's games have been played as originally scheduled though the Wildcats managed to get in a Nov. 29 win over Grambling State. That game was part of a substitute multi-team event after the Wildcats pulled out of the NIT Season Tip-Off, which was canceled later anyway.
The Wildcats are scheduled to face Eastern Washington on Saturday, with the Eagles being a late substitution for Northern Colorado, which had announced a COVID-related pause on Nov. 25.
