Harlequins have made three changes to the squad that will play in the World Club Sevens this weekend at Twickenham stadium.

Charlie Walker and Louis Grimoldby have been recalled into the senior squad to play in the pre-season friendly against Section Paloise (Pau) at the Stoop to cover minor knocks picked up by other squad members against FC Grenoble last weekend.

They have been replaced by Gavin Dampies, who represented the club in the Premiership Rugby Sevens finals, and Maika Burenivalu, a utility back, who is part of the Army's 17 Port & Maritime Regiment in Southampton.

Warren Abrahams has also been replaced by Bletchley RFC's Simon Pitfield, who also represented the club in the recent Premiership Rugby Sevens Finals.

Sam Stuart will captain the side.

Harlequins squad: Izzy Fao'i, Jack Maslen, Ian Clark, Sam Aspland Robinson, Simon Pitfield, Senitiki Nayalo, Al YamoYamo, Charlie Piper, Jordan Burns, Maika Burenivalu, Gavin Dampies, Sam Stuart (c).
