Rio Olympics 2016: Great Britain Sevens pick Allen, Bennett & Simpson
Great Britain Sevens have named 15-a-side internationals Cory Allen, Mark Bennett and Joe Simpson in their extended squad for the Rio Olympics.
Wales centre Allen, Scotland centre Bennett and England scrum-half Simpson are in a 25-man party which will be reduced to 12.
Uncapped Scarlets flanker James Davies, Harlequins back Ollie Lindsay-Hague and Newcastle's Marcus Watson are included.
Team GB's women's squad of 23 includes 21 England players.
Wales' Jasmine Joyce and Stephanie Johnston of Scotland are the only non-English players named.
England sevens captain Tom Mitchell and Wales skipper Luke Treharne are among the sevens specialists in the men's squad.
Although the likes of Allen, Bennett, Simpson and Davies are recognised 15-a-side players, they all have considerable sevens experience.
Bennett and Davies represented Scotland and Wales respectively at the 2014 Commonwealth Games and both have also played in the Sevens World Series, as has Cardiff Blues centre Allen.
"Exciting talent was available to us and competition for places was tough," said head coach Simon Amor.
"We're now really looking forward to bringing this group together as one team and creating an incredible Great Britain spirit."
The 25 players will meet on 30 May for a seven-week training period involving four international competitions, before the squad is cut to 12 in July.
