World reacts to the death of American sports icon Bill Russell

Bill Russell, a Pro Basketball Hall of Famer, Boston Celtics legend, and icon of American sports, has died at the age of 88.

He is regarded as the ultimate winner.

He won 11 NBA titles in a 13-year span, including eight in a row from 1959 to '66.

He holds the NBA Finals records for championships, appearances, game played, rebounds and minutes.

He also won two NCAA titles at the University of San Francisco and a gold medal in the 1956 Melbourne Olympics.

Russell's 11 pro championships are tied, with Henri Richard, for the most by any athlete in NBA, MLB, NFL and NHL history. Russell was also a powerful civil rights leader.

In 1961, he led a player protest when Celtics players were denied service in a Lexington, Kentucky, restaurant.

In 1963, along with Martin Luther King Jr., Cleveland Browns running back Jim Brown and Kareem Abdul-Jabbar, Russell stood with boxer Muhammad Ali, who refused to be drafted into the Vietnam War.

In 2017, Russell publicly supported athletes protesting during the national anthem.

The sports world joined together to mourn and honor Russell

RIP to our HERO!!! You are or will be always in our minds.
