Iowa State coach Fred Hoiberg has open-heart surgery

Iowa State says coach Fred Hoiberg has undergone open-heart surgery to replace aortic valve.
Hoiberg had surgery Friday at the Mayo Clinic in Rochester, Minnesota.
Doctor Rakesh Suri says the operation was a success, adding that "Hoiberg is in recovery and doing very well himself."
Hoiberg retired from the NBA following the 2004-05 season because of 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.
Hoiberg is expected to need about 4-6 weeks to recover.
