Mavericks owner Mark Cuban gave Derek Fisher a villain's welcome during the 38-year-old point guard's return to Dallas on Sunday night.

Fisher signed with the Oklahoma City Thunder in late February, approximately two months after the Mavs granted his request to be released, purportedly because the 17-year veteran missed his family. Cuban was admittedly agitated by Fisher's decision to return to the NBA without at least discussing the situation with him.

While Fisher expressed a fondness for Cuban and others in the Mavs' organization before Sunday night's game at the American Airlines Center, that feeling isn't mutual, at least as far as Cuban is concerned.

"I'll just boo him like hopefully everybody else," Cuban said before the game.

Mavericks fans were on board, too.

They booed Fisher when he entered the game with 1:45 left. They then cheered loudly 10 seconds later when the reserve guard was called for his first foul in Oklahoma City's eventual 107-101 win.

After Fisher signed with the Thunder, Cuban reacted with sarcasm, mockingly saying that Fisher's kids had grown up a lot in 65 days and that it was much easier to fly in and out of Oklahoma City than Dallas. On Sunday night, Cuban directly questioned Fisher's integrity.

"I took the bait," Cuban said.

Cuban said he was particularly perturbed by Fisher's decision to join a contender after quitting on the Mavs because the five-time NBA champion repeatedly reached out to Cuban when Fisher was unemployed at the beginning of the season. He said he offered Fisher personal advice and fell for the point guard's pitch, prompting the Mavs to sign him.

"My personality is to try to help somebody, particularly somebody that I thought one thing about, even if it didn't turn out to be that way," Cuban said. "So I was just trying to be nice and help. Usually when you help somebody, you expect at least some semblance of loyalty back. When you don't get it, then it's more disappointing.

"With his history, I shouldn't have been surprised what happened."
