Mavericks point guard Rajon Rondo and his head coach Rick Carlisle were clearly not on the same page during a game against the Raptors last night. And it has some people questioning what role Rondo will play with the Mavs moving forward.

With about eight minutes remaining in the third quarter of the contest, Carlisle tried to call a play out to Rondo as he dribbled up the court. Rondo ignored him, though, which forced Carlisle to call a timeout. And during that timeout, the player and coach spent almost the entire time yelling at one another. They had to be separated by one of the Dallas assistant coaches, and Rondo spent the remainder of the game on the bench.

"It's an emotional game," Carlisle said during his post-game press conference, "and we had a difference of opinion. There was an exchange, and then in my mind, it was over."

Rondo refused to talk about the altercation. "Discuss with Rick," he said.

But Mavericks owner Mark Cuban was more than willing to downplay the incident, especially since Dallas ended up winning 99-92.

"Shit happens," he told ESPN Dallas. "Not the first time, not the last time. It'll happen again. It's not just Rajon. It's a long season. In my 15 years, I've seen it happen more times than I can count, and we survive every time."
