How come chad michael murray wasnt at the 5th one tree hill basketball charity event?

i was looking at all the videos on youtube and chad michael murray wasnt at the 5th james lafferty charity basketball/ one tree hill! anyone know why? where was he??

I'm not sure why he wasn't there. I do know that he was filming a scene at the airport Friday. Alot of people saw him as they were coming into Wilmington. He told them he wasn't going to be able to make it, bit I'm not sure of the reason. Hilary Burton also wasn't able to make it. She had to attend someones bridal shower.
