From the Associated Press :

Mavericks guard Darrell Armstrong was so happy his beloved Washington Redskins beat the Dallas Cowboys that he grabbed a microphone before Sunday night’s game against the Minnesota Timberwolves and hollered, “How ’bout those Redskins!”

It’s going to cost him $1,000.

Dallas coach Avery Johnson announced the fine during his postgame news conference and team owner Mark Cuban later verified it was legit, much to the chagrin of a disbelieving Armstrong. The money will all go to charity, with Johnson saying the Cowboys would decide the recipient.

The Redskins wrapped up a 35-7 victory over the Cowboys shortly before the Mavericks left the locker room to play the Timberwolves.

Clearly, there’s no such thing as freedom of speech in the NBA. Can you imagine how much salary Armstrong would have to give back if he’d yelled “how ’bout that Lee Harvey Oswald?
