After dropping to the floor, Molina's teammates noticed that he was swallowing his tongue, which prompted them to reach into his mouth and clear the airway.
Following treatment from the medics on the pitch, Molina eventually got to his feet and walked off the pitch, later heading to the hospital for further tests.
According to Yahoo! Sport, Molina wrote on Twitter that he now "feels fine" and that he has been resting at home since the incident.
Molina's wife Laura was watching in the crowd when the clash occurred at Busan I'Park.
