In the eighth minute of their Fifa men’s World Cup match against England, Iranian goalkeeper Alireza Beiranvand collided face-first with a teammate. The clash left the keeper bloodied, unsteady on his feet, and apparently disoriented - in no state to play.
But after lengthy treatment he played on. Within minutes he had fallen to the floor and was carried off on a stretcher. He was later taken to hospital.
Former England player, Jermaine Jenas, who was commentating on the match, said the situation was “ridiculous” and “out of order”. Given the serious nature of Beiranvand’s injury, medical knowledge suggests he should have been taken off the pitch immediately.
