It has not yet been determined why Udoka is being suspended, beyond a “violation of organizational guidelines,” or whether the discipline is being handed down by the Celtics or NBA (or both).
Wojnarowski added that Udoka’s job is not believed to be in jeopardy, though the suspension could be significant.
Udoka was scheduled to meet with reporters on Monday for Celtics Media Day. Boston opens training camp on Tuesday.
“I do think there is clarity looming on the possible length of this suspension will be,” Wojnarowski said on ESPN, via Brian Robb of MassLive. “Perhaps in the next 24-48 hours. I think that is coming. This is moving quickly here in recent days. For this Boston organization on the cusp of training camp scheduled next week, this is certainly a significant derailment for them.”
Sources told Robb added that Joe Mazzulla may be the frontrunner to be named the Celtics’ interim head coach.
Prior to his coaching career, Udoka was a small forward with the Lakers in 2004, then spent time with the Knicks, Trail Blazers, Spurs and Kings from 2006-11. He also played professionally overseas.
According to ESPN Stats & Information, Udoka “became the first rookie coach to win multiple Game 7s in his first postseason,” Wojnarowski wrote.
