Mavericks owner Mark Cuban has denied claims that fans in Dallas made "continuous" racial taunts towards the Nuggets in their second round series.

Denver coach George Karl said on the Dan Patrick Show that pointed remarks were directed at his players by fans at American Airlines Center.

"I felt it crossed the line," said Karl. "There was a racist mentality to it. There was a fighting mentality to it. It was to the point where blows I think could have happened. There wasn't enough security."

Cuban fired off an e-mail response on Thursday, defending his team's fans.

"I don't want this to drag on and wish the Nuggets all the best going forward," Cuban wrote.

"The better team won the series. However, the mischaracterization of Mavs fans and the suggestion that there was a continuous racial or other type of onslaught by Mavs fans in the area toward the Nuggets bench and their fans is absolutely incorrect."
