NBA champion LeBron James, Super Bowl winner Patrick Mahomes and Japan's Naomi Osaka were among five athletes honored Sunday by Sports Illustrated (SI) magazine for their off-field activism.

SI's annual Sportsperson of the Year was The Activist Athlete and paid tribute to off-field activities by James, Osaka, Mahomes and his NFL teammate Laurent Duvernay-Tardif and Women's NBA champion Breanna Stewart.

James, who sparked the Los Angeles Lakers to the NBA title, spoke out on police brutality, racial inequality and championed a voter registration program, More Than A Vote, that helped sign up more than 10,000 poll workers as well as register voters in combating voter suppression.

Osaka won her third Grand Slam tennis title at this year's US Open. She took part in Black Lives Matter protests this year following the death of George Floyd and wore black masks during her US Open run, each with the name of an African-American killed by police.

Super Bowl Most Valuable Player Mahomes sparked the Kansas City Chiefs to the Super Bowl crown, pushed the NFL to recognize the Black Lives Matter movement and backed the right of NFL players to conduct social protests.

Duvernay-Tardif, the starting right offensive guard for the Chiefs but also a doctor, gave up his NFL uniform for doctor's protective personal equipment when the COVID-19 pandemic struck, joining the front line of a battle for people's lives.

Stewart supported Black Lives Matter from the start of the Women's NBA bubble to the finish, when she helped the Seattle Storm claim a fourth ­title and winning WNBA ­Finals MVP honors.
