June 6 (UPI) -- No women made the cut for Forbes' list of the top 100 highest-paid athletes of 2018.
Tennis sensation Serena Williams is typically among the top earners in sports. Williams ranked No. 51 in 2017, pulling in $27 million. Williams and Maria Sharapova were the only women on the list in 2016 and 2015.
Boxer Floyd Mayweather Jr. topped the 2018 edition of the list, raking in a total of $285 million. "Money" made $275 million in salary/winnings -- with the bulk of that coming from his fight against Conor McGregor -- and $10 million in endorsements.
The list included athletes from 22 countries in 11 sports. The 100 men earned a cumulative $3.8 billion over the last 12 months.
"Congrats to all of the athletes who made the Forbes list," Mayweather posted on Instagram. "You all are true champions."
McGregor was one spot behind Ronaldo, at $99 million. "The Notorious" was No. 24 on last year's list, earning $34 million. He earned more than some of the world's biggest starts, including No. 5 Neymar ($90 million), No. 6 LeBron James ($85.5 M), No. 7 Roger Federer ($77.2 M), No. 9 Matt Ryan ($67.3 M) and No. 16 Tiger Woods ($43.3 M).
"King James" edged Golden State Warriors foes in No. 8 Stephen Curry ($76.9 M) and No. 11 Kevin Durant ($57.3 M) as the NBA's top earner. He also earned the second-most money from endorsements, at $52 million.
Federer made the most money in endorsements at $65 million.
