Former England coach Eddie Jones will return to Twickenham in May to lead the Barbarians against a World XV.
Jones was sacked by England last week after seven years in charge as he paid the price for the team's worst run of results during a calendar year since 2008.
England won only five of 12 Tests in 2022, a miserable streak that came after Jones led them to three Six Nations titles and the 2019 World Cup final.
The 62-year-old Australian is set for a quick return to the headquarters of English rugby union with Barbarians.
Jones previously coached the Barbarians in a 33-31 defeat by Fiji in 2019.
“It’s an incredible honour to be asked to coach the Barbarians for a second time,” said Jones in a statement.
“The club showed during the autumn that the values and traditions which make the Barbarians so special are still very much alive. Fans can expect to see two top-quality teams, packed full of international players, going all out to catch the eye ahead of the Rugby World Cup.
“I am very much looking forward to returning to Twickenham Stadium – a venue I have so many fond memories of – as head coach of the Barbarians, and I’m more motivated than ever to put on a show.
“Going up against Steve rekindles a great rivalry which first started in our days competing in Super Rugby and progressed into the international arena. It’ll be a great challenge and one I’m sure we’re both relishing.”
He will take on a world side coached by former All Blacks boss Steve Hansen on May 28.
“2023 is set to be an incredible year for rugby and I’m really excited to be returning to Twickenham," Hansen added.
“I’ve coached both for and against the Barbarians during my career, and while you always have to expect the unexpected where they are concerned, you can be certain that come Sunday 28 May we’ll have a hugely entertaining match played in a festival atmosphere.
“The Rugby World Cup will be firmly on the horizon when this match comes around, and we hope we can showcase many of the players who will go on to be stars of the tournament in France during this Killik Cup clash.”
