The 46-year-old soccer referee passed away Saturday at 9:33 p.m. at Intermountain Medical Center, where he remained in a coma after he punched by the teen, according to a press release by the Unified Police Department.

Portillo was punched during at youth match at Eisenhower Junior High School in Taylorville on April 27. He had issued a 'Yellow Card' after seeing a goalkeeper pushing another. But the goalkeeper retaliated by punching him on his head, as he was jotting down notes in his notebook.

Soon after, the referee reportedly started to vomit blood after feeling dizzy, according to the Salt Lake Tribune. His condition worsened after he was taken to hospital where he fell into a coma and eventually died.
