Mike Krzyzewski's Friday morning lower-back surgery "went exactly as planned," said Dr. Allan Friedman, who added Duke's Hall of Fame coach is "in terrific physical shape" and that a "full recovery" is expected.
A fragment of a herniated disc was removed.
Krzyzewski is expected to miss four weeks of games.
This surgery comes two days after the eighth-ranked Blue Devils welcomed Grayson Allen back from a one-game suspension and beat Georgia Tech 110-57 to improve to 13-2 overall and 1-1 in the ACC.
