Iker Casillas suffered a heart attack in training, though Porto released a statement saying that his life was not in danger.
“Iker Casillas suffered an acute heart attack during this Wednesday’s training session. The session was quickly halted so medical assistance could be provided to the Porto goalkeeper, who is currently in the CUF Porto Hospital. Casillas is ok, stable and the heart problem has been resolved," said the club.
The 37-year-old Casillas joined Porto in 2015.
