Three days after suffering a concussion, Tyler Hansbrough bodied up to the ballhandler near the North Carolina bench when he was inadvertently elbowed in the face and fell to the floor.

Before Coach Roy Williams or anyone there could fret, the junior All-American bounced right up and played with his typical intensity.

Too bad the top-ranked Tar Heels as a whole couldn't say the same.

Hansbrough had 27 points and 11 rebounds while showing no visible effects from the concussion, but North Carolina's Hall of Fame coach was seething at a lethargic performance in an 88-78 victory over Nicholls State on Wednesday night.
