Dieng, who had surgery on his left wrist earlier in the week after breaking the scaphoid bone last week against Missouri, smiled at several reporters and said the surgery "went good," on his wrist.
The 6-foot-10 Dieng is expected to be out four-to-six weeks – the official timeline – but U of L coach Rick Pitino said on his radio show on Wednesday night that his gut told him the junior could return in three weeks.
Pitino then said he "doubted" Dieng would be playing until five weeks and likely wouldn't be back for the Dec. 29 game against Kentucky.
"The good thing is the surgery went well, the screw went right in," Pitino said.
Pitino said Zach Price and Stephan Van Treese "did an admirable job" filling in for Dieng during the Duke game on Saturday. But he said he told his team that "we're not going to replace Gorgui."
"They can't pass and block shots like Gorgui," Pitino said. "I said it's time for Chane (Behanan) and Wayne (Blackshear), Kevin (Ware), Peyton (Siva) and Russ (Smith) and all the guys to step up and play better than they've played."
Pitino later said to a group of reporters that: "It's up to the rest of our guys to just play better. We're not going to replace Gorgui."
