Celtics coach Doc Rivers corroborated with what forward Kevin Garnett released in a statement on Wednesday regarding an exchange with Detroit's Charlie Villanueva on Tuesday night.

"I'm not going to go off on a tangent about this whole thing," Rivers said before Wednesday's game against Milwaukee.

"I actually heard what Kevin said, I was sitting right there. What he released is what he said and I'm going to leave it at that."

Villanueva wrote on his Twitter page that Garnett referred to him as "a cancer patient" during Boston's victory over Detroit.

Garnett released a statement saying that he was calling Villanueva "cancerous to your team and our league."

Rivers wouldn't discuss the exchange further, but he did offer his opinion on Twitter in general.

"I don't like the whole Tweeting thing," he continued. "I'll state that as well. Guys talk on the court, whether they should or shouldn't, but the fact that we're talking about this is just silly."

Rivers then joked that he would Tweet every bad question asked by reporters.
