Everton boss Roberto Martinez has backed calls to stop managers making decisions on players with concussion, reports BBC Sport. Tottenham keeper Hugo Lloris was knocked unconscious after a collision with Toffees striker Romelu Lukaku but continued after lengthy treatment.
"If there is a strong view from the medical side that a concussed player should come off we should look into it and make a rule," said Martinez.
"I don't think it should be a manager's decision whether you take a player off or not.
"It should be part of the game and a law. It would be very unfair to be a manager in a position where you have to take a player off just to avoid any sort of risk without having that medical knowledge."
