The sister-in-law of late NBA trailblazer Jason Collins shared insight into his final months before his death from brain cancer. "Obviously it's been a tough day, a tough year," Elsa Collins, who is married to Jason's twin brother, Jarron Collins, said in a video posted to her Instagram Story on Tuesday, May 12. Earlier that day, it was announced by the family that Jason, the first openly gay player in NBA history, had died after being diagnosed with Stage IV glioblastoma in November 2025. He was 47 years old.
