Salt Lake City ? Utah Jazz center Greg Ostertag, a former Kansas University player, is expected to miss at least three games because of an abdominal strain resulting from donating a kidney to his sister in the offseason.

A Jazz spokesman said the strain was not career-threatening and that trainers were being cautious holding Ostertag out of Utah’s loss Tuesday night.

“He’s out there playing right now,” Jazz spokesman Kim Turner said from the team’s practice Wednesday. “It’s just an abdominal strain. It’s just something from the surgery still, something that he’s going to have to get through.”

Ostertag is expected to travel on a three-game road trip that begins in Cleveland on Friday, and he might play in the third game, in New York, on Oct. 22.

The 29-year-old Ostertag donated a kidney to his younger sister, Amy Hall, in June. Hall, 26, has had type 1 diabetes since she was 7.
