Bath Rugby centre Jonathan Joseph returns to the England team for their Rugby World Cup Pool A game against Australia at Twickenham on Saturday (k.o. 8pm).
Anthony Watson is also in the starting line-up, on the right wing, while Rob Webber, George Ford and Sam Burgess are named on the bench.
Joseph returns from a chest injury to take over from Brad Barritt, who shifts back inside centre for Burgess. Ben Morgan replaces the injured Billy Vunipola at number eight.
Joe Launchbury (Wasps) comes in for the injured Courtney Lawes (Northampton Saints) for his first World Cup start and Nick Easter (Harlequins) is included on the bench for his third tournament following his call-up for the injured Vunipola to provide specialist No 8 cover. George Kruis (Saracens) gets his first RWC matchday experience in the 23.
England Head Coach Stuart Lancaster said: “JJ and Ben Youngs are both fit and raring to go, as are the rest of the squad for what will be a huge game against a very good team. England-Australia matches at Twickenham are always massive occasions, this one more than ever, and we want everyone behind us so we can get the result we all want.”
