The Boston Celtics pounded the Detroit Pistons on Tuesday, and Charlie Villanueva posted messages on his Twitter account that indicate Kevin Garnett may have made it personal.

One of the tweets says: "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."

Garnett is known for his trash-talking on the court. Villanueva suffers from alopecia universalis, a medical condition that results in hair loss. The Detroit forward does not have hair on his head.

The Pistons confirmed that Villanueva posted the tweets but had no further comment.

Garnett called the incident "a major miscommunication."

Before the Celtics' win over the Bucks on Wednesday he released a statement.

"My comment to Charlie Villanueva was in fact 'You are cancerous to your team and our league,'" Garnett said. "I would never be insensitive to the brave struggle that cancer patients endure. I have lost loved ones to this deadly disease and have a family member currently undergoing treatment. I would never say anything that distasteful. The game of life is far bigger than the game of basketball."

After the game Garnett said: "I'm a passionate player. If you don't like the way I am ... I play this way the last 15, 16 years. I leave it on the court."

Villanueva had posted multiple tweets saying that Garnett's alleged comments hit home.

"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," the tweet reads.

Garnett scored 22 points and had six rebounds in the Celtics' 109-86 victory. Villanueva had 17 points and seven rebounds off the bench for the winless Pistons. Villanueva was ready to take the battle off the court.
