Vunipola called up for expectant father Marler

RBS SIX NATIONS:

The Saracens player steps in because Marler will miss the climax to the 2014 RBS 6 Nations campaign as his partner is expecting their first child.

Vunipola will be promoted to the starting XV, with 23-year-old Marler staying in London to be present at the birth rather than accompany the squad to Rome.
