Charlie Villanueva was pretty calm and sounded contrite after the Pistons dropped their home finale tonight to the Cleveland Cavaliers.

But that's a sharp contrast to his meltdown during the fourth quarter.

Villanueva could be subject to some type of league discipline after being ejected and restrained twice from going after the Cleveland Cavaliers' Ryan Hollins.

"You gotta be careful with the quiet ones, right?" said Villanueva, normally gregarious. "At the end of the day that's something that happened on the court, it should stay on the court.

"I overreacted. He said some things that got me upset."

With 5:47 left in the Pistons' 110-101 loss, Villanueva and Hollins started wrestling with each other when Villanueva went to set a pick.

Both were pulled back to their respective benches and things appeared calm, but after both players were ejected, Villanueva sprinted across the Palace floor toward the Cavs' locker room.

He was grabbed by Rodney Stuckey and Pistons security head Jerry Hendon and they were able to get him under control.
