The decision to let Iran goalkeeper Ali Beiranvand play on after a head-on collision with a team-mate against England has been branded an "utter disgrace" by brain injury charity Headway.
Beiranvand had got a hand to a Harry Kane cross in the sides' World Cup opener in Doha on Monday but in doing so collided face first with team-mate Majid Hosseini and was in need of treatment for several minutes. Incredibly, Beiranvand was allowed to play on despite the clash of heads leaving him with a bloodied nose.
Moments later, however, the former Royal Antwerp stopper was carried off on a stretcher to be replaced by Hossein Hosseini. Luke Griggs, Headway's interim chief executive, could not believe what he was witnessing.
