While the Champions Cup confrontations were revealed a little earlier, we also know the posters for the Challenge Cup round of 16. Aviron Bayonnais, returned to the competition after its elimination in the Champions Cup, will travel to Edinburgh. Clermont, after a good run, will host the Cheetahs while Montpellier will host Ulster, also reversed. The Castres will travel to Gloucester – who have already beaten them this weekend – and Pau will play against Connacht. The matches will take place on the weekend of April 5, 6 and 7.
