Haris Seferović was hit on the head with a ball while waiting to come on as a substitute for Switzerland during their 1-0 defeat to Sweden.

The Benfica striker was about to be introduced to the field of play alongside Breel Embolo when a ball came flying at him out of nowhere.

Whether the ball was thrown by an errant ball boy or a supporter from the stands is not clear.

Emil Forsberg’s deflected effort in the second half saw Sweden triumph in the World Cup Round of 16 match at the Saint Petersburg.
