Mavericks' forward Josh Howard was filmed disrespecting the American National Anthem, and the video was posted on YouTube.

Howard is shown at Allen Iverson's charity flag football game in July. When the national anthem is being sung, various participants are shown mugging for the camera. When the camera gets to Howard, he says, "'The Star-Spangled Banner' is going on. I don't celebrate this [expletive]. I'm black."

The Mavericks claim they already knew about the incident, and owner Mark Cuban dealt with it back in July when it happened.

"That said, we will be going through some advanced communication-skill sessions together this training camp," Cuban said Tuesday. "I have explained to him that cellphone cameras are not your friend and that what you think you said on camera is never what people will hear when it shows up on YouTube or TV."
