Iowa State's Fred Hoiberg to be released after open-heart surgery

AMES, Iowa -- The Mayo Clinic says Iowa State coach Fred Hoiberg is expected to be released Thursday, less than a week after open-heart surgery.

Hoiberg had surgery at the clinic in Rochester, Minnesota, on Friday to replace his aortic valve, a procedure he put off twice during the season.

Hoiberg is expected to need four to six weeks of recovery before returning to work.

Hoiberg retired from the NBA following the 2004-05 season following heart issues. He just completed his fifth season at Iowa State, leading the Cyclones to four straight NCAA tournament appearances and back-to-back Big 12 tournament titles.
