The competition will kick off on Friday, September 27th and there will be three rounds of games before a break for the weekend of the World Cup quarter-finals on October 19th and 20th.

The Pro 14 is expected to confirm its schedule in the coming weeks, almost six months after the French and English announced their plans for the 2019-20 season.
It is believed that uncertainty over the number of South African teams participating – there were strong suggestions a year ago that two more teams were planning on joining – may have been a factor in the delay announcing the schedule.
The uncertainty over the regional situation in Wales is not believed to be a factor as the WRU is committed to fielding fourth teams.

The Top 14 final will take place on June 26th, 2020, while a date and venue for the Pro 14 final is expected to be announced in the coming weeks amid speculation in South Africa that the tournament decider could be hosted there.
