Segundo Castillo's clash with Luis Montes was one of the most gruesome images of the day as Savage Saturday came to a close having four more players added to the list of World Cup non-participants.
There was a great deal of angst from the Mexican camp after Montes suffered his tibia and fibula fracture; Castillo was diagnosed with a torn ACL and he will be missing the World Cup as well.
Ecuador coach said that Montes' challenge was "imprudent". "I didn't see (the play) but I believe there was a bit of precipitation in that 50/50 ball," said Rueda. "It's unfortunate that this occurs because it is now a streak of two or three World Cups in which national teams lose important players."
Castillo's injury was reported by Cancha Ecuador when it was diagnosed officially that he had a complete tear of the ligament. At the end of the match, there was an initial prognosis of a partially torn cruciate ligament, but the severity of it was not known until the player arrived at a local hospital in Dallas minutes after the incident occurred.
Castillo is the second injury of note on the Ecuadorian national team after Jayro Campos suffered his just a few months before.
