Due to the terrorist attacks that took place in Paris on 13 November 2015, matches in the European Rugby Champions Cup and European Rugby Challenge Cup were postponed to a later date – later announced to take place on the weekend of 8–10 January 2016. This meant the fixtures that featured those teams in their respective domestic leagues, were postponed to a later date. This meant that the entire Round 13 schedule was postponed: one match was moved to mid-February, and the remaining six matches were moved to mid-March.
