Porto goalkeeper and Real Madrid legend Iker Casillas is reported to be in a stable condition after suffering a suspected heart attack.
Reports in the Portuguese Press claim Casillas fell ill during training with Porto on Wednesday and was rushed to hospital.
The 37-year-old underwent emergency surgery and is described as being ‘out of danger’.
It now remains to be seen whether the Spaniard will be able to continue his playing career.
Casillas is one of the most decorated players in Spain’s history, playing over 700 games for Madrid before joining Porto in 2015.
He won three Champions Leagues with the capital giants, as well as two European Championships and a World Cup in his 167 caps for La Roja.
