"We've made the decision to hold Tyler Hansbrough out of action a little
longer," Williams said on Wednesday. "It's extremely doubtful that he would play against
Pennsylvania, and I emphasize extremely doubtful.
"We will continue to
evaluate him and have more information when it becomes available."
Hansbrough has been sidelined since the last week of October with a stress reaction in his right shin.
The senior from Poplar Bluff, Mo., has played in all 108 games the Tar Heels have played in over the previous three seasons.
