Arguably the most important player to this year's Duke team, five-star freshman Harry Giles, underwent his third knee surgery in the past three years on Monday.
Duke announced Monday afternoon that an arthroscopic procedure on Giles' left knee was "successful." Giles is expected to miss six weeks, which calls into question the start of the season.
A six-week recovery would put him on track to return on Nov. 14. Duke's first game is on Nov. 11., at home, against Marist. But the first big game comes four days after that: the Champions Classic tilt vs. Kansas at Madison Square Garden on Nov. 15. Giles' availability for that game is to be determined, but with a knee scope this close to the season, it wouldn't be a shock to see Krzyzewski opt to ease him back into the lineup.
