Duke's Kyrie Irving could miss the rest of the season with a right toe injury suffered in the second half of Saturday's win against Butler.
Irving, an early candidate for freshman of the year, didn't break a bone but the injury involves ligaments.
"Kyrie's injury is a serious one," coach Mike Krzyzewski said after Duke beat Bradley on Wednesday night. "
Duke will not rush Irving back from injury, according to a source.
Irving is widely considered a future top-five NBA pick.
