There's only so much stress the body can take. Mike Krzyzewski learned that the hard way.

Duke Aren't The Favorites To Win NCAA Title

The Duke basketball head coach wasn't present at the team's 80-71 win over Georgia Teach on Tuesday night. Krzyzewski attended practice on Monday, but began to feel ill when the team arrived at the airport to leave for Atlanta.

ESPN's Jeff Goodman revealed why after the game.

Fortunately for the game of college basketball, all of the tests administered to Krzyzewski came back fine. He's expected to rejoin the team on Wednesday, except this time off the strength of a win.

Something that can finally put his mind at ease.

"He was dehydrated and hasn't been getting enough sleep," a source told ESPN.

Losing four of your last five will do that to you. Before Tuesday's developments, Krzyzewski saw his 14-2 record dwindle to a sub-standard 15-6 mark.

Even worse, Duke fell out of the AP Top 25 for the first time since the 2007-08 season.

Tuesday's win, however, could serve as the turning point for both coach and team. With some time away to recover -- no matter how brief -- Krzyzewski can now zero in on February's stretch run to March Madness.

A sixth national championship depends on it.
