According to press release from Duke Basketball, five-star freshman forward Harry Giles had successful knee surgery on Monday and is expected to miss six weeks.

With Duke slated to face Kansas in this year’s Champions Classic at Madison Square Garden on Nov. 15, Giles’ availability for that Top 5 showdown is in question, given the fact that Nov. 15 is exactly six weeks from Tuesday.

Even if he is available for the Champions Classic, he almost certainly will miss the Blue Devils’ season opener, Nov. 11 against Marist, and, therefore would be playing his first ever college game on the biggest stage imaginable against another blue blood program.

Regardless of what it means for the start of Duke’s season, Duke coach Mike Krzyzewski said everyone was in agreement that surgery was the right move.

“We’re very pleased with the outcome of today’s procedure,” Krzyzewski said in the release. “This is the right step for Harry at the moment as it will help him be 100 percent going forward. Harry has done a tremendous job in rehabilitation over the last year and I’m sure he’ll continue to do the same after this procedure.”

The operation was the third knee surgery in the past three years for Giles, a 6-foot-10, 240-pound forward from Winston Salem, North Carolina.
