They're headed back to the Gallagher Premiership.
Declan Kidney's London Irish have secured a swift return to the Gallagher Premiership.
The Exiles, who were relegated last season, are set for promotion after a bonus-point 46-7 victory over Richmond.
TJ Ioane and wing Ben Loader grabbed two tries each with Albert Tuisue, Bryce Campbell, Josh McNally and Alivereti Veitokani also crossing the whitewash.
Irish, whose final league game is against second-placed Ealing Trailfinders next week, are assured of promotion with a game to spare.
Sean O’Brien is set to join the club next season, with Australia scrum-half Nick Phipps's signing also secured.
Irish chief executive Brian Facer paid tribute to the team's achievements.
“We have achieved our return to the top tier of English rugby, which was the only objective at the start of the season. I would like to congratulate and thank Declan Kidney, his coaching team and the players for working tirelessly over the last year to ensure this was possible.
“I would also like to thank our President, Mick Crossan, and the Board for their support and our on and off-field teams for all of their hard work.
“To all our supporters, thank you for following the team home and away, enjoy the celebrations.”
