There exists a promotion and relegation system between the Top 14 and Pro D2. From the 2017–18 season, the bottom club after the regular season is relegated to Pro D2 and replaced by the Pro D2 champion, now determined by a six-team knockout playoff. The second-from-bottom Top 14 side enters a playoff with the runner-up of the Pro D2 playoffs, with the winner either remaining in or promoted to Top 14. Since the
2009–10, the knock-out stages for the Top 14 have involved six teams and consist of three rounds. The top two teams on the ladder receive a bye into the semi-finals, while the next four teams on the ladder play in the first round, with the third and fourth-place teams each hosting a match. The winners of those matches face the top two teams in the semi-finals, which are held at neutral sites, and the semi-final winners advance to the final at
Stade de France (the traditional site, although the
2016 final was held at
Camp Nou in
Barcelona due to conflict with
UEFA Euro 2016). With Europe's former top club competition, the Heineken Cup, being superseded by the
European Rugby Champions Cup from
2014–15, the qualification method for all nations changed slightly. This, however, did not affect the number of French teams assured of Champions Cup qualification—as in the Heineken Cup era (1996–2014), six Top 14 teams are assured of Champions Cup places in the following season. The top six teams on the Top 14 table earn Champions Cup places. A seventh French club can qualify by winning a play-off following the club season. From the 2016–17 season forward, this playoff will involve the seventh-place teams from the Top 14 and
English Premiership, plus the top two teams from
Pro14 that (1) did not automatically qualify for the Champions Cup and (2) are not from South Africa. All Top 14 teams that do not qualify for the Champions Cup, including the teams newly promoted from Pro D2, will play in the
Challenge Cup. ==Pro D2==
