The world's first openly homosexual basketball player Jason Collins has announced his retirement from the sport.
Collins, 35, came in April 2013, going on to play for Brooklyn Nets last season, but failing to make their squad this time around.
"I am officially announcing my retirement from the NBA," Collins said in an interview with Sports Illustrated.
"As we speak I'm watching a college basketball game but it's time for me to truly become just a fan and watch from the sidelines.
"My body was talking to me, my body was telling me that it was time. I think as older generations can understand that when you wake up in the morning and it feel likes starting an old car.
"My lower back, my knees, it was one of those things that my body was letting me know as it does with so many other professional athletes."
Jason Collins has made his debut for the Brooklyn Nets, becoming the first openly gay player to play in a competitive game in the NBA.
