GREENVILLE, S.C. (AP) Mike Krzyzewski's emotions began to flow with a few seconds left on the clock, when it was finally certain Duke would extend his last NCAA Tournament run.

He whirled around to face the section where his family was sitting behind him and extended both arms to point their way in celebration. He traded high-fives and hugs with his players, then shared a long postgame hug at midcourt with Michigan State's Tom Izzo after beating his friend in the Hall of Fame coaches' bittersweet final tussle.

Krzyzewski's retirement will be on hold for several more days at least. The Blue Devils survived a tense finish to beat the Spartans 85-76 on Sunday, earning another trip to the Sweet 16 and giving their coach his latest milestones.
