Jamal Musiala, 23, collapsed twice in Bayern Munich pre-season friendlies within four days, first on August 15 against RB Leipzig and again on August 18 against Heidenheim [1, 2, 3, 4]. Both incidents came shortly after he entered the matches as a substitute, around six to eight minutes in each time [1, 3, 4].

The first collapse occurred in Munich during a match with RB Leipzig where temperatures exceeded 30 degrees Celsius, initially considered a contributing factor [1, 2, 4]. Despite scoring a goal, Musiala collapsed and needed medical attention [1, 2, 4, 5]. Three days later, in the 4-2 win over Heidenheim, he collapsed again appearing dazed and was treated on the field [1, 2, 3, 4].

Following medical evaluation, Musiala was diagnosed with a neurological disorder that causes brief, temporary absence seizures which explain the episodes on the field [2, 3, 4, 5, 6, 7]. The seizures are treatable, and Musiala reported no long-term health risks. He said, "I have been diagnosed with brief, temporary – but treatable – absence seizures resulting from a neurological dysfunction. These can lead to the kind of incidents seen recently" [4].

Musiala expressed optimism about his condition, stating, "I am receiving excellent medical care and remain very optimistic. Importantly, there is no further health risk involved" [4]. On social media, he added, "First things first — I'm doing well! I am incredibly grateful for your messages and your support! I want to put those worries to rest today and explain the situation" [6]. He also said, "I have taken full responsibility for this decision. Overall, I feel very positive and am on the right track" [6].

Bayern Munich sporting director Max Eberl acknowledged the club’s awareness of Musiala’s condition and said the player would address it publicly soon. "Jamal will speak about this in the near future. We knew about it and we are aware of the situation," he said [1].

Musiala missed six months of the 2025-26 season due to an ankle injury sustained at the 2025 Club World Cup but returned to play later and represented Germany at the 2026 World Cup [1, 2, 5]. He has made 231 appearances for Bayern Munich [3].

Musiala revealed his diagnosis publicly on August 19, 2026, using social media to update fans and clarify his health status [2, 3, 4, 5, 6, 7]. The club and player continue to monitor the situation as Musiala receives treatment.
