Guard Seth Curry will miss No. 2 Duke's game against Delaware on Saturday with what the school says is an injured left ankle.
It's the first game Curry has missed since he became eligible after transferring from Liberty following the 2008-09 season, and he had played 78 straight games for the Blue Devils before this.
He injured his ankle while coming off a screen during the second half of the win over No. 4 Ohio State on Wednesday night.
Curry averages 15 points and two rebounds this season and is the team's second-leading scorer.
