England pick Twelvetrees & Clark

Uncapped pair Billy Twelvetrees and Calum Clark have been named in a 33-man England squad for the Six Nations. Gloucester centre Twelvetrees, 24, has forged an effective club partnership with Freddie Burns, who is one of three fly-halves in the squad. Northampton flanker Clark, 23, served a 32-week ban last season for breaking Leicester hooker Rob Hawkins's elbow. Burns, lock Joe Launchbury, hooker Tom Youngs and prop Mako Vunipola are formally promoted to the senior squad. England kick oftheir Six Nations campaign against Scotland at Twickenham on 2 February. The requirement for an eight-man replacements' bench means senior squads have been increased to 33 players, with Vunipola the additional prop. Head coach Stuart Lancaster is confident Clark has learned his lesson from the Hawkins incident and that he has both the temperament and the ability to succeed at the highest level.
