LONDON – Retired England international Joe Marler will face his country next month after he was named on Monday in the Barbarians squad for this weekend’s fixture.

Prop Marler, 28, announced a shock retirement in September due to family reasons, but still plays for club Harlequins, and is among a 23-man side name by the invitational outfit coached by Pat Lam.

Former Australia captain James Horwill will play his final game on Sunday before hanging up his boots.

The squad also includes World Cup winners Colin Slade, Liam Messam, Malakai Fekitoa and John Afoa, as well as Wales scrumhalf Rhys Webb, who is ineligible to feature at this year’s tournament as he plays outside his home nation and has fewer than 60 caps to his name.

England have named an inexperienced group for the uncapped fixture containing youngster Marcus Smith, who will miss the Under-20 World Cup in Argentina due to the call-up.

Welsh-born Bristol playmaker Callum Sheedy is another option at flyhalf for head coach Jim Mallinder.
