But U of L coach Rick Pitino said that doesn't mean Dieng will make a decision at the end of the season to put his name into the NBA Draft.
"I'm not pushing him out the door," Pitino said. " It's not a decision I am making. It's not a decision he's making. It's a decision we let the pros make."
Dieng will go through Senior Night festivities along with seniors Peyton Siva and Mike Marra before Saturday's 4 p.m. game against Notre Dame.
"We're honoring him on Senior Night," Pitino said. "I told him that I want to honor him because I think he's a first-round draft pick.
"Not that it matters what I think because I don't work for the Celtics anymore."
The 6-foot-11 Dieng is averaging 9.9 points and 10 rebounds a game for the Cardinals (25-5, 13-4).
Pitino said he spoke with Dieng prior to the season and the talk was that if he was a first-round pick then he needed to turn pro.
"We have not discussed it since," he said. "We talked about it before the year. If he is drafted in the first round, he leaves. If he isn't, then he comes back.
"When the time comes we'll deal with it."
Dieng, who will meet with the media on Friday afternoon, told Cardinal Authority after the Cincinnati game on Monday that he doesn't "worry about anything but trying to win games right now."
"I worry about things that are going to change the score (for the Cardinals). I don't worry about anything with me. My goal is to beat Notre Dame."
