On Monday, February 9, Nikola Topic, a promising NBA prospect for the Oklahoma City Thunder, made a remarkable return to basketball following a year-long knee injury and a testicular cancer diagnosis. This comeback came after Topic completed his cancer treatment and recovered sufficiently to play again.
The 20-year-old Serbian player made his debut with the Oklahoma City Blue, the Thunder’s G-League affiliate, contributing seven points and seven assists during a thrilling 137-135 overtime victory against the Sioux Falls Skyforce. This marked a significant milestone for Topic as he looked to resume his professional career after facing serious setbacks.
Background on Topic’s Injury and Cancer Diagnosis
Topic was selected 12th overall in the 2024 NBA Draft by Oklahoma City, but a torn knee ligament sustained two months before the draft forced the team to delay his playing debut for nearly a year. Just a few games into the 2025 season, Topic was dealt another blow when he was diagnosed with testicular cancer, putting his basketball aspirations on hold once again.
Despite his diagnosis, Topic maintained a rigorous training routine during chemotherapy, a testament to his determination and resilience. General Manager Sam Presti shared the team’s approach during this challenging period, emphasizing patience and support without rushing Topic’s recovery.

He’s been in here, he’s training, he’s working out,
Presti said during media interviews, highlighting the player’s commitment to staying active despite his health issues.
Completion of Treatment and Return to Play
According to Topic’s agent, who spoke with Serbia’s Arena Sport TV on February 8, the player had successfully finished chemotherapy and was prepared to fully reengage with basketball activities. This optimistic update came just a day before his G-League return.
The Thunder’s head coach, Mark Daigneault, expressed his excitement on seeing Topic back in action, acknowledging how important this day was for the young athlete’s mental and physical well-being.
We’re all just collectively thrilled that he’s back playing basketball,
Daigneault said.
I know he’s missed it a great deal, and this is just so good for him mentally to get his feet back underneath him.
Coach Highlights Topic’s Strength and Resilience
Daigneault praised Topic not only for his talent but for the courage and maturity displayed throughout his difficult journey. The coach emphasized that regardless of what the future holds for Topic in the NBA, his return to the court is a profound achievement after two years away from consistent play.
Just can’t say enough about him as a guy, his mental toughness, maturity, resilience,
Daigneault remarked.
He hasn’t played a lot of basketball over the last two years, and he comes off a one-year rehab and immediately has a surprising diagnosis and goes through chemotherapy, three rounds of it. So for him to work himself back onto the court is just an unbelievable accomplishment, and we’re incredibly happy for him.
Looking Forward: What Topic’s Comeback Means for His Career
Nikola Topic’s return signifies not only a personal victory over physical and medical adversity but also gives hope to athletes facing similar challenges. His journey reflects the importance of perseverance and mental strength in professional sports.
While it remains uncertain how his NBA career will develop moving forward, Topic’s successful comeback demonstrates that with unwavering dedication and support, obstacles—even ones as severe as cancer—can be confronted and overcome.
