After leaving his team's 74-72 win over Wake Forest on Tuesday at halftime because he wasn't feeling well, Duke coach Mike Krzyzewski updated his status on Thursday ahead of the No. 9 Blue Devils' game with Florida State on Saturday. The 75-year-old legend, who is retiring after this season, said on ESPNU Radio that "I'm better," and he attributed the issue to the rigors of a busy schedule.

"We went through a very taxing part of our season with four games in eight days, late travel," Krzyzewski said. "I still prepare the same way. That day for Wake, I wasn't feeling that good. But during the game, during the first half, I got lightheaded on the bench. I called (assistant coaches) Jon Scheyer and Chris Carrawell over and said, 'I'm not feeling great, you guys do more. Don't hold back.' Then I started feeling a little bit better during the half, and then as I'm walking off the court at halftime, it's the first time I had stood up. I really thought I could pass out."

Krzyzewski said he received IV treatment after returning to the locker room. The Blue Devils had to sweat out a close win without him, but Krzyzewski was feeling well enough to speak with the team after the game.

"You get exhausted," he said. "I don't know if it was my way of celebrating my 75th birthday and saying, 'knucklehead, you are 75 and you better do something a little bit different.' I am better, and I'm glad that it was that and not something else. My guys did a really good job and we were able to beat a really good Wake Forest team."
