• Despite experiencing symptoms like muscle soreness and dark urine, Sendler continued training, mistaking the signs for dehydration.
• He collapsed after a fight on March 3, 2025, and was hospitalized with what doctors described as the most severe case of rhabdomyolysis they had ever seen.
• Sendler underwent multiple surgeries but ultimately passed away due to extensive tissue damage and multi-organ failure.
• His family has launched a GoFundMe campaign to raise awareness about rhabdomyolysis and advocate for education on its early symptoms to prevent similar tragedies.
