"After falling to 0-4 on Tuesday, it's clear that the Pistons are stinging from more than just the team's losses. Pistons forward Charlie Villanueva posted a message to his Twitter account on Wednesday morning that he was bothered by Celtics forward Kevin Garnett calling him a "cancer patient."

"KG called me a cancer patient, I'm pissed because, u know how many people died from cancer, and he's tossing it like it's a joke," Villanueva wrote. "I wouldn't even trip about that, but a cancer patient, I know way 2 many people who passed away from it, and I have a special place 4 those."

Before talking about Garnett's insult, Villanueva seemed to give the Celtics forward an open invitation for a fight."
