Smith, who injured the second toe on his left foot late in the conference quarterfinals Friday night, had been considered a game-time decision.
Team spokesman Matt Plizga said Saturday that X-rays taken on Smith's injured toe showed that it wasn't broken.
Smith, the conference player of the year, was hurt with 6:48 remaining in what appeared to be a non-contact injury. He planted in the lane and tried to jump but instead fell to the floor.
He limped off the court, and team medical staff removed his left shoe and evaluated and tested his foot. Smith put his shoe back on and walked off the bench and into the tunnel with 5:21 left in the game, which Duke won 87-71 over Maryland.
He returned to the bench a few seconds later to a standing
ovation from the Duke fans but could be seen limping.
Smith averages an ACC-best 21.6 points for the Blue Devils
(28-4), the No. 2 seed in the league tournament.
