Michael Ray Richardson Cause of Death: NBA All-Star Dies at 70 After Prostate Cancer Diagnosis

Michael Ray Richardson, a four-time NBA All-Star known for his dazzling playmaking and elite defense, has died at the age of 70. His death was confirmed by the New York Knicks and reported by ESPN on November 11, 2025. The former Knicks, Warriors, and Nets guard passed away shortly after being diagnosed with prostate cancer.

Nicknamed “Sugar,” Richardson was one of the most dynamic guards of his era, remembered for his electrifying steals, court vision, and charisma on and off the court. Tributes from across the basketball community have poured in following the news, celebrating both his talent and his story of redemption.

Michael Ray Richardson Cause of Death Confirmed by Family and ESPN

According to ESPN, Richardson’s longtime attorney and friend, John Zelbst, confirmed that the former NBA star died after being diagnosed with prostate cancer. The Knicks released a statement honoring Richardson, calling him “one of the fiercest defensive players of his era” and expressing condolences to his family and friends.

“He made an incredible impact on the Knicks during his four seasons with the franchise,” the team said, noting his four All-Star selections. The Brooklyn Nets also released a message, saying, “We’re saddened to hear of the passing of former Nets All-Star, Michael Ray Richardson. The Nets family sends their deepest condolences to the Richardson family today.”

Richardson’s story was one of both brilliance and resilience. He was drafted in the first round in 1978 and quickly became known for his all-around game — averaging 14.8 points, 7 assists, 5.5 rebounds, and 2.6 steals per game across eight NBA seasons. In 1985, he earned the NBA Comeback Player of the Year Award after rebounding from personal struggles.

However, in 1986, Richardson was banned for life from the NBA due to violations of the league’s drug policy. He later found redemption overseas and through his autobiography, Banned: How I Squandered an All-Star NBA Career Before Finding My Redemption, where he reflected on overcoming adversity and reclaiming his life.

Tributes and Legacy of ‘Sugar’ Richardson

Tributes have poured in from fans, former players, and media figures who remembered Richardson not only as a skilled player but as a man who changed his life for the better. “He lived life to the fullest. He overcame the most incredible odds,” Zelbst told ESPN, adding that Richardson was “the greatest NBA player never to make the Hall of Fame.”

Fans have echoed those sentiments online. One wrote on social media, “Was very blessed to meet you last year during your book signing. World class gentleman. Rest In Power, Michael Ray Richardson.” His son, Amir Richardson, has carried his father’s competitive legacy, building his own career as a professional soccer player in France.

Richardson’s journey — from stardom to scandal to redemption — remains one of the most compelling in basketball history. His impact on the game and his example of personal growth have made him an enduring figure in NBA lore.

Michael Ray Richardson’s cause of death was prostate cancer, but his life story remains one of triumph over adversity — a reminder of resilience, forgiveness, and enduring legacy in the sport he loved.
