Christian Wade has been called up by the British and Irish Lions and withdrawn from the England side to play Argentina in Buenos Aires today.
The Wasps wing, who made his Test debut in a 32-3 victory over the Pumas in Salta last weekend, has been replaced in the England team by Gloucester debutant Jonny May.
Wade is the third England player to be summoned to Australia from England's South American tour, following prop Alex Corbisiero and centre Billy Twelvetrees.
The Lions have concerns over the fitness of wing George North, who has a tight hamstring, while centre Jamie Roberts suffered a leg injury in their victory over the NSW Waratahs today.
England coach Stuart Lancaster said: "We're delighted for Christian. He's been in excellent form, played really well on his Test debut against Argentina last weekend and he goes with the best wishes of all the England players and management.
"Jonny May comes into the side to win his first cap against the Pumas today. He's been an important part of our squad over the last four weeks, he's up to speed with everything we're doing and this is a great opportunity for him."
Wade has been preferred to the likes of Chris Ashton, who has been rested from England's summer tour, and Scotland's Tim Visser to give the injury-hit Lions additional back line options.
Lions coach Warren Gatland said: "We have obviously got ongoing treatment of some players so it's prudent to make sure we have enough backline cover.
"Christian played well in the first Test against Argentina and is match fit."
