The five-year contract extension signed last August by Detroit Lions quarterback Matthew Stafford not only, at the time, made him the highest-paid player in the NFL, it made him the highest-paid athlete, anywhere.

Stafford ranks No. 10 on Forbes' list of the world's highest-paid athletes for 2018, posted Tuesday.

Stafford, who signed a five-year $135 million extension in August that's since been surpassed by quarterbacks Jimmy Garoppolo (San Francisco 49ers), Kirk Cousins (Minnesota Vikings), and Matt Ryan (Atlanta Falcons) for the NFL's largest in history, will pull in $59.5 million in 2018, according to Forbes — $57.5 million in "salary/winnings," and another $2 million in endorsements.

Ryan checks in at No. 9 overall, pulling in $67.3 million in salary/winnings and endorsements following a five-year $150 million extension he signed last month. Cousins, the Holland native and former Michigan State star, is No. 55 at $28.4 million ($26.9 million in salary; $1.5 million in endorsements) for 2018.

Boxer Floyd Mayweather, a Grand Rapids native, tops the list with 2018 earnings of $285 million.

Also on the list: Pistons forward Blake Griffin, who checks in at No. 30, at $35.5 million ($29.5 million in salary; $6 million in endorsements); Tigers first baseman Miguel Cabrera is at No. 54 at $29.2 million ($28.7 in salary; $500,000 in endorsements); and Pistons center Andre Drummond is No. 74 at $24.9 million ($23.9 million in salary; $1 million in endorsements)

Former Tigers pitcher David Price (Boston Red Sox) is at No. 47 ($30.7 million), former Tigers ace Justin Verlander (Houston Astros) is at No. 53 ($29.4 million); and former Tigers outfielder Yoenis Cespedes (New York Mets) is No. 71 ($25.2 million).
