Oxford University student Jamie Gibson has been called into the 27-man England squad for the Killik Cup clash against the Barbarians at Twickenham.

The London Irish flanker is one of four players added to the squad that will tour South Africa, with players from Aviva Premiership finalists Leicester and Harlequins unavailable.

England head coach Stuart Lancaster said: “This is a great opportunity for the rest of the squad to put a marker down before we leave for the tour.”
