Jason Collins, the historic NBA veteran who broke significant barriers as the first active male athlete in a major American professional sport to come out as gay, has passed away at the age of 47. His family confirmed that his death followed a long and difficult struggle with glioblastoma, an aggressive and inoperable form of brain cancer. Collins had been transparent about his diagnosis since 2025, facing the illness with the same tenacity that defined his 13-season professional career.

Drafted into the league in 2001, Collins played for six different franchises, most notably serving as a key defensive presence for the New Jersey Nets during their back-to-back Eastern Conference championship runs. However, his most enduring contribution to the sport occurred in 2013, when he penned a landmark essay publicly announcing his sexuality. The move sparked a global conversation about inclusivity in athletics and earned him a place on Time Magazine’s list of the 100 most influential people, fundamentally shifting the culture of professional team sports.

In the years following his diagnosis, Collins pursued aggressive medical interventions, including specialized chemotherapy treatments in Singapore and the use of targeted therapies like Avastin. Throughout his treatment, he remained a vocal advocate for living authentically, often drawing parallels between his health journey and his decision to come out. He frequently spoke about the importance of personal freedom and the courage required to live one’s truth, leaving behind a legacy that transcends his on-court statistics.

Members of the basketball community, including former coaches and teammates, have paid tribute to his character and impact. Former Stanford University coach Mike Montgomery remembered Collins as a brilliant, skilled athlete whose influence on the sport and the university remains profound. The Brooklyn Nets organization also honored his memory, describing him as a thoughtful and kind individual who possessed a unique ability to bring people together both on and off the court.
