DURHAM - Coach Mike Krzyzewski addressed the media just moments ago about the upcoming NCAA Tournament where his Blue Devils will play in Charlotte.  The big news was that Kyrie Irving was clear and participated in practice today.  Krzyzewski said that more would be known by the open practice in Charlotte on Thursday and BDN will be there to bring you the very latest.  Irving would see spot duty while he re-acclimated himself to the team and worked into playing shape.  Coach said he was ahead of schedule and that the injury was healing nicely.  Kyle Singler said, "He hasn't missed a beat, but is not in the shape he needs to be."
