Germany star says neurological issue behind two collapses in a week

Bayern Munich and Germany star Jamal Musiala says a neurological issue is behind him collapsing twice in a pair of friendlies this week. Musiala, 23, says he has been diagnosed with temporary "but easily treatable absence seizures", and added that there was "no additional health risk". What's next? Bayern is next in action against Borussia Dortmund at 4:30am AEST on Sunday. It is unclear whether Musiala will be ruled fit to play. Bayern Munich midfielder Jamal Musiala has revealed a neurological issue but says he is doing well despite collapsing during a preseason game for the second time in a week. The 23-year-old Germany international went down shortly after entering Wednesday's (AEST) friendly as a substitute in the second half. Players from both teams made a circle around Musiala as he received medical treatment. He was then helped as he walked off the pitch. Musiala had collapsed Sunday (AEST) during a friendly against Leipzig. German news agency DPA reported he had left the field on his own but still appeared dazed. Loading Twitter content After Wednesday's game, Musiala posted a message on his Instagram account, explaining that he had been diagnosed with temporary "but easily treatable absence seizures" caused by a neurological problem. "These can lead to the moments that happened recently, such as against Leipzig or even now in Heidenheim," Musiala wrote. Bayern, in its report on Wednesday's game, only said of the incident: "There was a setback when Jamal Musiala had to be subbed off with a knock minutes after coming on." Musiala said he was "very optimistic" and was receiving excellent medical treatment. "The important thing is that there is no additional health risk," he wrote. "In close coordination and regular communication with experts, it has been my personal wish to face the challenge and, with the endorsement of the neurological specialists, to devote myself to what helps me most in recovery: to simply live my everyday life and keep up with my passion of playing football," Musiala added.
