A change in medication.Mockito 23‑year‑old Jamal Musiala collapsed twice in recent friendlies, according to Bayern Munich head coach Vincent Kompany. Musiala had been treated for a "neurological dysfunction" that triggers brief, treatable seizures, and the club confirmed awareness of(delay) the condition before the World Cup and early in the season.

Kompany explained that a "slight" adjustment to Musiala’s medication caused the incidents against RB Leipzig and Heidenheim. He added that such changes are normal and that the team has worked closely with leading experts. Musiala’s Instagram post acknowledged the seizures as part of his everyday life, while neurologist Dr. Meneka Sidhu detailed the nature of absence seizures—short episodes of loss of awareness that can happen to athletes.

Sidhu advised identifying triggers such as hyperventilation and dehydration, noting that properly treated absence seizures should not impede sport participation. The situation mirrors other elite athletes, like rugby player Tommy Freeman, who manage epilepsy while competing at high levels.

Bayern maintain full support for Musiala as they continue to monitor his condition closely.
