Jordan Henderson is doubtful for England's semi-final clash with Croatia on Wednesday.

The Liverpool captain has a tight hamstring and the medical staff will try and get him fit for the big match, while the rest of the team returns to training on Monday.

Henderson has started in all but one of the Three Lions' games in Russia so far, and ran two kilometres more than any other player in the last-16 win over Colombia after extra time.

Striker Jamie Vardy is also under question mark after suffering a groin strain in the same duel.
