<div class="inside-copy"> CHAPEL HILL, N.C. (AP) - The father of reigning national player of the year Tyler Hansbrough said Friday it's unclear if the North Carolina star will miss any regular-season games because of a leg injury. </div> <p class="inside-copy">Gene Hansbrough told The Associated Press his son had felt pain in his right shin off and on for a few weeks before going to the team's medical staff. The team said Hansbrough will be out of practice indefinitely with a stress reaction, which can be a precursor to a fracture without proper rest.</p> <p class="inside-copy">"It's something they picked up early and it should be resolved I hope fairly quickly," he said in a phone interview. "The smart thing is to get it resolved instead of having Tyler limp through it."</p> <p class="inside-copy">Gene Hansbrough said further tests revealed no new information. He said it's too early to tell whether Hansbrough will miss the top-ranked Tar Heels' opener against Penn on Nov. 15, and recovery will depend on rest for the injury and then getting into shape.</p> <p class="inside-copy">Later Friday, coach Roy Williams said in a statement Hansbrough would likely be evaluated in two weeks.</p> <p class="inside-copy">"It's kind of frustrating for Tyler," Gene Hansbrough said. "As much as he likes to play, he understands he needs to be 100% to help the team rather than limping through something and make an injury a chronic situation."</p>
