Lakers forward Ron Artest was critical of head coach Phil Jackson on his Twitter page.

Artest began expressing his frustration on his Twitter page, @RONARTESTCOM, late Thursday night.

The first unedited tweet read: "Finally Phil Jackson didn't mention me in media before talking me Now I can build on game 2. Hopefully he talks to me before the media."

The next unedited tweet came about an hour later: "Ever since phil mention things about me in media before coming to me first I was weird . So every pray he can somehow close his yapper."

At Friday's practice, Artest would neither confirm nor deny that the tweets were his.

"I'm here to talk about basketball, basketball, all basketball," Artest said. "Twitter is for my fans, not for [media]."
