Smith out with mild concussion

DURHAM, N.C. -- Duke sophomore Nolan Smith is out indefinitely with a mild concussion suffered in a win at Maryland.

The point guard was injured when he collided with Dave Neal after the Terrapins center set a hard screen near the foul line in the second half of Duke's 78-67 victory on Wednesday night.

Smith collapsed to the floor and stayed there for several minutes before leaving the game. He did not return.

The school said team medical staff examined Smith after they returned home that night and again Thursday. Duke coach Mike Krzyzewski said Smith had improved, but added that the team was going to "proceed cautiously."

Smith is averaging about 9 points per game for the No. 7 Blue Devils, who play Saturday at Virginia Tech.
