Mavs owner Mark Cuban called the suspension "unbelievable" in an e-mail to The Associated Press.
"Michael Finley does a pile driver with his hip to Jason's head while he is on the ground," Cuban wrote.
"Jason is on his back with Ginobili laying on top of him. No question he tried to get Finley off of him and he should be fined for that. But to suspend him is questionable."
Interviewed on Terry's radio show, Cuban said he "didn't understand it and not quite so politely, I told the league so." He added that after watching replays from five angles, he considered it more of a reaction than a punch. "If that's a punch, Jason certainly didn't get his money's worth," Cuban said. "If his hand would've been open to get Fin off him, we wouldn't be having this conversation. But the fact that his fist was closed when he reacted to him, they call it a punch."
