Salt Lake City ? Greg Ostertag was suspended indefinitely by the Utah Jazz on Thursday for his conduct after a loss to Seattle.

The center did not show up for practice Thursday morning, a day after playing less than 10 minutes in a 113-94 loss to the SuperSonics.

“We did not tell him not to come to practice,” said Kevin O’Connor, Jazz vice president for basketball operations.

Ostertag’s agent, Jeff Austin, did not return messages from the Associated Press on Thursday. Ostertag told The Deseret Morning News on Thursday that he had told O’Connor he wouldn’t be at practice.

O’Connor, who would not elaborate on what got Ostertag suspended, said he told Ostertag that wasn’t acceptable and he was expected at practice Thursday morning.

O’Connor planned to meet with Ostertag and coach Jerry Sloan to get the matter resolved soon.

Sloan and Ostertag have had several clashes since the Jazz took Ostertag out of Kansas University in the first round of the 1995 draft.

Ostertag has played in 41 games this season, his first back in Utah after spending a year in Sacramento. He played his first nine seasons with the Jazz.

Utah plays Saturday at Dallas, where Ostertag is from, and plays host Monday to San Antonio. The Jazz already have a shortage of players because of injuries and had just 10 players available against the Sonics.
