Coach K leads Duke practice

— -- DURHAM, N.C. -- Coach Mike Krzyzewski was out of the hospital and at practice Thursday with No. 4 Duke after feeling light-headed during a loss at Wake Forest the night before.

Team spokesman Matt Plizga says Krzyzewski led practice. Krzyzewski said in a text to ESPN.com he was doing much better.

Duke hosts No. 14 North Carolina on Saturday (9 p.m. ET on ESPN, WatchESPN App) in the regular-season finale for both teams.

Earlier in the day, the school issued a statement that Krzyzewski was taken to Duke University Hospital in Durham for a precautionary examination after the 82-72 loss in Winston-Salem. He was sent home in the early morning after the school says his condition improved.

The 67-year-old Hall of Fame coach took a knee during a timeout in the second half of Wednesday night's game. He did not attend the postgame news conference.

Associate head coach Steve Wojciechowski said after the game that Krzyzewski had not been sick and has been in good physical shape.
