#3. Joe Marchant to Stade Francais
The 26-year-old, who has earned 14 caps in the past four years, heads to the Top 14 after nine years at The Stoop.
Marchant came through the Quins academy and has made 140 appearances since his debut in 2014.
He follows England team-mates Luke Cowan-Dickie and Sam Simmonds in opting to pause his international career in order to play overseas.
Commenting on his departure at the end of the season, Marchant said: “I am very proud and grateful to have been part of Harlequins for the last 10 years.
“I’ve made some amazing memories on and off the field and made great friends along the way. This club has been a home to me and will always have a place in my heart.
“The time has come for me to depart the Club and I am excited for my next challenge ahead. I will make the most of every moment for the rest of this season proudly wearing my Quins shirt.
“Thank you for all the support!”
