Fixtures:
Sunday, 19 January – Bordeaux-Begles v Sharks (13:00 GMT), Toulouse v Leicester Tigers (15:15)
Ulster’s bonus-point win over Exeter Chiefs secured at least Challenge Cup rugby, leaving the Chiefs without any more European rugby this season.
Richie Murphy’s side still have a chance of reaching the Champions Cup last 16, but must hope Bordeaux thrash Sharks on Sunday by a big enough margin for them to go through on points difference.
Sharks need a point from their final game to reach the last 16, while Leicester Tigers, Toulouse and Bordeaux have all qualified.
Leicester face champions Toulouse on Sunday knowing a win could secure one of the top two seeds and home advantage in the last 16.
Maximum points for Bordeaux against Sharks will secure their spot as top seeds. Failure to do so will hand Toulouse or Tigers an opportunity to steal top spot.
