Mike Krzyzewski has hernia surgery

Duke basketball coach Mike Krzyzewski had surgery on Monday morning to repair a hernia. On April 3, Krzyzewski underwent total knee replacement surgery on his left knee.

"I'd like to thank everyone at Duke University Hospital who made this procedure as smooth as possible," Krzyzewski said in a statement. "With this surgery behind me, I'll be in great physical condition heading into the Olympics and I'm excited for the opportunities that lie ahead."

Average recovery time from hernia surgery is four weeks. Krzyzewski should be better to coach the U.S. Men's National team in the Summer Olympics in August in Rio de Janeiro.

The 69-year-old Krzyzewski is 75-1 as coach of the U.S. team, which includes an active 63-game winning streak. His teams have won two Olympic gold medals.

Krzyzewski has won a Division I men's record 1,043 games in 41 seasons at Duke, including five NCAA titles.
