Marcus Smith has been called up to the British and Irish Lions squad for their tour of South Africa, as Finn Russell struggles with an Achilles tendon injury.
Fly-half Smith, 22, helped Harlequins to the Premiership title this season and made his England debut against the United States last week.
He followed up his international bow with a superb showing in a 70-14 demolition of Canada on Saturday, kicking nine conversions.
After impressing at Twickenham, Smith – following coronavirus testing – will be heading to South Africa to join up with the Lions, who faced the Sharks on Saturday in their third match of the tour, with the three-Test series against the Springboks starting later this month.

And Gatland is excited to see what Smith can bring to his squad, with Russell likely to be out for several weeks.
"Finn Russell has been managing an Achilles injury he's had for a couple of weeks, but he's not going to be 100 per cent," Gatland explained.
"He's got a slight tear in his Achilles, they're going to inject it and see if they can manage it through the next couple of weeks, as a result we're going to call up Marcus Smith to come out here on Sunday.
"He'll catch a flight, needs to be PCR tested after the [England] game and hopefully all is well. He's been absolutely outstanding, I'm a big fan of his, watched him play last year, thought he was really promising, had a great season for Harlequins.
"He's been playing regularly, winning the championship with Harlequins, playing for England now and a similar player to Finn Russell so a like-for-like replacement in a lot of ways, so he might add something exciting and new to the squad."
