Floyd Mayweather Drops Off Forbes' List, Lionel Messi Takes Top Spot

From #1 to not even listed ... Floyd Mayweather is NOT one of Forbes' highest-paid athletes of 2019 ... after taking the top honors one year ago.

The business magazine released its list of the richest ballers of the year ... and surprisingly, the boxing superstar nicknamed "Money" ain't on it.

The top 3 spots belong to footballers Lionel Messi ($127 million), Cristiano Ronaldo ($109 million), and Neymar ($105 million) ... and Canelo Alvarez ($94 million) and Roger Federer ($93.4 million) round out the top 5.

Look, this ain't a shot at Floyd -- considering he made more than double what Messi made this year in 2018 (he raked in $285 million thanks to the Conor McGregor fight) ...but it's interesting to see him fall out of the top 100 altogether.

Other notable athletes in the top 10 include Russell Wilson ($89.5 million), Aaron Rodgers ($89.3 million) and LeBron James ($89 million).

McGregor made the list at #21 with $47 million earned (last year he was #4 with $99 million).

As for cash made straight off endorsements, King James ain't at the top -- it's Federer, with $86 million made off the tennis court.
