Warriors will start their European Challenge Cup campaign with a trip to France to play Pau in their opening match in the preliminary stage on Saturday December 12 (kick-off 8.00pm GMT).

Warriors will then host Ospreys at Sixways on Saturday December 19 (kick-off 8pm) in a match that will be shown live on S4C.
The return match against Ospreys will be played at Liberty Stadium on Friday January 15 – also live on S4C – where Warriors will be looking for a repeat on their success of January 2019 where a last-gasp drop goal from Ryan Mills snatched a dramatic win.
