Jamal Musiala collapsed on the pitch for the second time in a matter of days during Bayern Munich's friendly victory against second-division side Heidenheim.
Teammates shielded Musiala as doctors rushed onto the field, and following brief treatment, he left the pitch looking dazed.
Musiala collapsed in worrying fashion during Bayern's win over Leipzig on Saturday, but returned to action off the bench against Heidenheim.
The Bavarians won the match 4-2 in a dress rehearsal for the Franz Beckenbauer Supercup this Saturday against rivals Borussia Dortmund, but this incident has yet again overshadowed the contest.
After the match, sporting director Max Eberl said Musiala would make a comment on the situation soon.
"Jamal will speak about this in the near future. We knew about it and we are aware of the situation," Eberl said.
"Jamal will speak out. He's in the dressing room, getting changed and taking a shower."
