There still is no word whether the nation's second-best rebounder will turn pro or return to Colorado for his senior season.
Junior forward Andre Roberson and Buffaloes coach Tad Boyle were scheduled to discuss his decision at a news conference Friday morning, but that briefing was canceled and the school said there are "currently no plans at this time to reschedule."
The deadline for non-seniors to announce their status is Sunday.
Roberson led the Pac-12 with an 11.2-rebounding average to go with his 10.9-point scoring average and helped the Buffaloes reach their second straight NCAA tournament for the first time in a half-century.
At 210 pounds, Roberson lacks the size of prototypical rebounders but makes up for it with his leaping ability and skills around the basket.
