Citing an unnamed source, the Milwaukee Journal Sentinel reported Sunday that Bogut also suffered a broken right hand in Saturday's game against Phoenix when he fell awkwardly after making a slam dunk in the second quarter.
The source said Bogut, a fifth-year pro, was taken to Aurora Sinai Medical Center in Milwaukee for evaluation and tests showed the extent of his injuries. The newspaper said the center will undergo surgery and won't be available for the Bucks' expected playoff run.
Milwaukee is on the verge of clinching a playoff berth, needing any combination of two Bucks wins or Chicago Bulls losses over the six remaining games to make the cut. Milwaukee could ensure a playoff spot with a win over the Bulls Tuesday night in Chicago.
"If Bogues is out, obviously we're going to rely on Kurt (Thomas) more," Bucks Coach Scott Skiles told the Journal Sentinel after Saturday's game. "He's played in 80 playoff games; he's played in the NBA finals. He's got a lot of experience in this type of race right now."
