Arizona basketball coach Lute Olson is getting divorced.

He filed a divorce petition in Pima County Superior Court on Thursday, the same day the 73-year-old coach said he would extend his leave from the team through the end of the season, Olson's lawyer, Leonard Karp, said yesterday.

"The marriage has been irretrievably broken with no reasonable prospect of reconciliation," Karp said.

He said Christine Olson, the Hall of Fame coach's second wife, is still living in Tucson.

Olson announced his leave Nov. 4, saying the reasons were personal and not health-related. In a statement released by the university Thursday announcing the leave extension, Olson said he plans to coach the Wildcats for the 2008-09 season.

Athletic director Jim Livengood, in Chicago with the team, said, "It's a personal family matter and should be addressed appropriately."

The No. 22 Wildcats (5-2) play Illinois today.

Olson has coached Arizona for 24 seasons and posted a 589-187 record with 23 consecutive NCAA Tournament appearances.
