Jamal Musiala health issues, explained: Why Bayern Munich star's 'absence seizures' cause him to faint

Bayern Munich and Germany star Jamal Musiala has struggled with injuries over the past few years, and the 2026/27 club season presented a fresh start from which to springboard back to his best after over a year of struggling with fitness.

Unfortunately, his preparations for the coming campaign have been halted in concerning fashion, as Musiala has suffered bouts of unconsciousness in consecutive preseason friendlies that have put both his immediate and long-term playing future at risk.

Musiala has collapsed during play in two different matches as Bayern Munich prepare for the upcoming season, which starts for the Bavarian giants on Saturday as they meet Der Klassiker rivals Borussia Dortmund in the DFL-Supercup.

The Sporting News explains what has been the issue for Musiala and what his prognosis is moving forward as he looks to continue his football career safely and responsibly.

Jamal Musiala on-field collapses

Bayern Munich playmaker Jamal Musiala has fainted in two consecutive preseason friendlies, sparking concern amongst the global football fanbase.

First, he fell to the ground during a 3-1 friendly victory over RB Leipzig on Saturday, August 15. He looked woozy on his feet, and new Bayern signing Ismael Saibari ran over to assist him, helping the dazed Musiala to the turf safely.

After that incident, Musiala recovered quickly and returned to training, with the medical staff clearing him of any larger concerns. "The most important thing is that he is well," said Bayern Munich executive Max Eberl to The Mirror after the match. "There's nothing more to say about anything else."

Bayern head coach Vincent Kompany, meanwhile, blamed the combination of significant heat and Musiala's recent medical struggles for the initial collapse. According to reports, medical tests revealed no significant issues, and he was cleared to continue playing.

What has Jamal Musiala said about his condition?

After the second incident in the friendly against Heidenheim, Jamal Musiala took to social media to reveal that his collapses have been due to a diagnosis of "absence seizures." The full statement on Instagram read:

I'm doing well! I am incredibly grateful for your messages and your support! I understand that many of you are worried. I want to put those worries to rest today and explain the situation.

I have been diagnosed with brief, temporary — but treatable —absence seizures caused by a neurological dysfunction. These can lead to the kind of moments that occurred recently, such as during the match against Leipzig or now in Heidenheim. I know they might look scary at first glance, but for me, they are currently just part of my everyday life. I am receiving excellent medical care for this and remain very optimistic. FC Bayern and my personal support network are right by my side, helping me through this. Importantly, there is no further health risk involved. In close consultation and regular contact with the experts, it was my personal wish to face this challenge head-on. With the medical clearance of the neurologists, I want to continue doing what helps my recovery the most: simply living my daily life and pursuing my passion for playing football. I have taken full responsibility for this decision.

Overall, I feel very positive and am on the right track. What helps me most on this journey is continuing to chase victories and titles with my team and with your amazing support. I hope this helps you understand my situation better. At the same time, I ask for your understanding regarding my wish to keep the details of this matter private—sharing them only with my closest circle, the club, and the medical experts.

Despite claims that the issue is relatively minor, it's hard to imagine that after two straight incidents, Bayern Munich would put him back on the pitch without reconsidering his condition and treatment plan moving forward to prevent more recurrences.

What are absence seizures?

Jamal Musiala revealed after his second on-pitch collapse that he had been diagnosed with "absence seizures" that were causing his recent issues.

According to Massachusetts General Hospital, absence seizures "cause a brief, temporary loss of awareness, usually for 5 to 30 seconds." An individual experiencing an absence seizure "may stare into space or look like they’re daydreaming." Usually, the individual returns to consciousness relatively quickly after an absence seizure.

These kind of symptoms can be managed by antiseizure medications. There are sometimes referred to as "petit mal seizures," which translates as “little illness” in French.

According to the Mayo Clinic, absence seizures are far more common in children, and it is rare that the symptoms persist into adulthood. However, they can sometimes be a precursor to a more serious kind of epilepsy that presents with what are known as "grand mal seizures."

It's unclear if Musiala has experienced these symptoms through his childhood, or if they have just recently begun.

Is Jamal Musiala's condition life threatening?

While this typically does not result in physical injury on most occasions, the situation in which the seizure presents could be extremely dangerous.

If the individual suffers a loss of consciousness during an activity that requires consistent attention, such as driving, riding a bike, or other athletic activity, it can create a situation that becomes dangerous by association.

Jamal Musiala age

Jamal Musiala is 23 years old.

The Massachusetts General Hospital writeup claims that absence seizures can begin in children ages 3 to 8 and are most common in those aged 8 to 15. "Although uncommon, some children continue to have absence seizures into adulthood," the article states.

He has been considered one of the best young players in the world for some time, but as he begins to reach the prime of his career, he has been beset with significant injury concerns.

Jamal Musiala injury history

As he transitions from his developmental years into the peak years of his career, Jamal Musiala has struggled mightily with injuries over the past few years.

At first, it began with muscle injuries, as he picked up a series of short-term issues with his hamstring in late 2023. He missed significant time with a hamstring injury in the latter half of the 2024/25 season, missing the final 71 days of the campaign as well as that summer's UEFA Nations League finals with Germany.

Then, the big injury struck as Musiala suffered a gruesome broken leg in the 2025 FIFA Club World Cup during a challenge from then-PSG goalkeeper Gianluigi Donnarumma, which saw him sidelined from July through the middle of January 2026.

Musiala returned from his fracture but suffered subsequent ankle issues that disrupted his time through the spring of 2026 and saw him fail to return to his best form by the World Cup later that summer.
