The Chelsea defender was replaced by Joleon Lescott after colliding heavily with team-mate Joe Hart following a push from Belgium's Dries Mertens in the 17th minute.

Cahill was substituted immediately and subsequently underwent an X-ray on his jaw to establish the severity of the injury.

England went on to win the match courtesy of a first-half goal from Manchester United striker Danny Welbeck, meaning Roy Hodgson has now won both of his first two games since taking the reins of the national side.

However, the injury to Cahill will concern the former Liverpool manager who has already lost both Gareth Barry and Frank Lampard from his original Euro 2012 squad due to injury.
