Ally Hogg, a regular in the back row for the past four seasons, and flying winger Thom Evans will lead Scotland's bid for glory in the events in London on May 23 and 24 and Edinburgh the following weekend.

It is the first time in recent years current Scotland Test players have turned out for the Sevens outfit but it makes sense for the duo to continue their season with the possibility of a Lions call always in the back of their minds.

Evans, who made his RBS 6 Nations debut this year, was close to the original selection and would be a leading contender if any of the wingers were injured in South Africa, while Hogg can cover for all three positions in the back row.

Evans missed Glasgow's last game of the season against Connacht with a calf strain but is expected to be fit for Sevens action.

Scotland Sevens coach Stephen Gemmell is delighted he has some full international class available to him this month.

He said: “There’s no substitute for out-and-out pace and to have a player the calibre of Thom Evans is fantastic. Couple that with the likes of Hefin O’Hare and Andrew Turnbull and we’ve got some of the fastest players in Scotland available.”
