A photo of basketball Hall of Famer and Boston Celtics legend Bill Russell kneeling while wearing his Presidential Medal of Freedom surfaced on social media Monday in an apparent gesture of solidarity to the sports world's reaction to President Donald Trump's comments on protesting NFL players.
"Proud to take a knee, and to stand tall against social injustice. #takeaknee #medaloffreedom #NFL #BillRussell #MSNBC," read the caption under a photo posted on an unverified Twitter account listed under Russell's name.
The account was created earlier this month and only had one previous tweet before the photo was posted. It was not clear if the account belongs to Russell.
The 83-year-old was awarded the Medal of Freedom, the nation's highest civilian honor, in 2011 by President Barack Obama. The civil rights activist has long fought for human rights and became the first black man to coach an NBA team.
Russell played for the Celtics from 1956-1969. The 11-time NBA champion later coached the Seattle SuperSonics and Sacramento Kings.
Trump's urging of NFL team owners to fire or suspend players who don't stand for the national anthem led to more than 200 players protesting, many kneeling, during the "Star Spangled Banner" at football games over the weekend. Owners, coaches, former players, celebrities and other athletes also joined gestures of solidarity and condemned the president's comments.
