Irish provinces will be involved in some heavyweight clashes to launch next season's Heineken Champions Cup and EPCR Challenge Cup in December.
The 2022/23 European campaign kicks off on the weekend of December 9/10/11, with Leinster, beaten Champions Cup finalists in May, travelling to face Racing 92 in a repeat of the 2018 decider, before hosting Gloucester the following week.
Munster's first round assignment will see them hosting Toulouse at Thomond Park as the teams meet for the first time since May's epic quarter-final. Graham Rowntree's side are off to Northampton Saints in round 2.
Dan McFarland's Ulster begin the tournament with their first ever Champions Cup trip to Sale Sharks, ahead of a mouth-watering match against reigning champions La Rochelle at Kingspan Stadium.
Meanwhile, in the Challenge Cup, Connacht are set to entertain Newcastle Falcons in their Galway opener. The westerners will visit Brive in the second round, facing former team-mates Sam Arnold and Abraham Papali'i.
At this stage, EPCR are only announcing the fixtures by round for the pool stages, with exact dates, kick-off times and TV coverage in both the Champions Cup and Challenge Cup to be announced as soon as possible following the conclusion of negotiations with broadcasters for the new cycle across each market.
Next year's two tournament finals, representing the pinnacle of elite European club rugby, will take place at the Aviva Stadium on Friday, May 19 (Challenge Cup) and Saturday, May 20 (Champions Cup). Click here for ticket information.
The European finals weekend returns to Dublin, and the home of Irish Rugby, a decade on from when Toulon defeated Clermont Auvergne to lift the famous silverware for the first time in 2013.
