Darryn Peterson, the electric Kansas guard widely projected as a potential No. 1 pick in the 2026 NBA Draft, has finally shed light on the mysterious health issue that derailed much of his freshman season. In a revealing interview with ESPN, Peterson shared that high-dose creatine use was the likely culprit behind the severe cramping that cost him 11 games and limited his availability throughout the year.

"I thought I was going to die on the training table that day," Peterson recalled, describing the terrifying episode during Kansas' preseason conditioning program that sent him to the hospital. The cramping started in his legs and rapidly spread to his entire body, leaving trainers unable to find a vein for an IV. "I made it to the training room and just started begging them to call 911."

Creatine, a popular supplement used to boost strength and muscle performance, is widely available and often taken by athletes. But Peterson, who had never used it before arriving at Kansas, learned through post-season bloodwork that his natural creatine levels were already elevated. Adding the supplement pushed them into an unsafe range, triggering the debilitating cramps.

The issue created a stop-start rhythm for both Peterson and the Jayhawks. Head coach Bill Self acknowledged that the uncertainty surrounding the guard's condition affected team consistency, though medical privacy rules limited what the program could disclose during the season. Peterson tried managing the problem with hydration, electrolytes, IV treatments, and dietary changes, but the symptoms kept returning.

Now, with a clear diagnosis and a plan to avoid the supplement moving forward, Peterson can focus on what he does best: dominating on the court. For NBA decision-makers weighing the No. 1 pick, this clarity might be the game-changer they've been waiting for. When healthy, Peterson is a dynamic playmaker with the size, skill, and basketball IQ to anchor a franchise—and now teams know exactly what caused the setbacks that made his freshman season such a rollercoaster.
