After receiving a letter from the NFL informing him of a $13,261 fine over his coin-flipping touchdown celebration in Week 18 against the Baltimore Ravens, Mixon took to Twitter to call the league out.
His message was simple: Have another coin toss and if it comes up heads, Mixon will pay the fine.
But if it comes up tails? NFL Commissioner Roger Goodell has to pay the fine money to the Boys and Girls Club of Cincinnati.
The NFL is unlikely to engage in this, of course, but Mixon has at least made a funny moment out of trolling the league with his celebration.

And if nothing else, Chad Johnson has offered to pay the fine.
