The NBA has fined Amar'e Stoudemire $50,000 for tweeting a gay slur at a fan over the weekend, Marcus Spears of Yahoo! reports.

On Sunday, Deadspin reported that a fan told Amar'e he needed to step his game up on Twitter.

Amar'e DM'd him back, writing, "F--- you, I don't have to do any thing f--."

Stoudemire later apologized to the fan, but the NBA still handed down a stiff punishment.
