(Reuters) - Prop Mako Vunipola has said that he and brother Billy have challenged themselves to come back stronger than ever from injury lay-offs, which forced them to miss the first part of England's Six Nations campaign.

The Saracens forwards have both returned from knee injuries, with Mako coming off the bench during a 36-15 victory over Italy, while number eight Billy is selected to face Scotland at Twickenham on Saturday.
