Saints are back in the Champions Cup - and they will find out who they will face in the pool stages when the draw takes place in Switzerland on Wednesday afternoon.
The draw will begin at approximately 1.20pm and will be streamed live on www.epcrugby.com and on the official Heineken Champions Cup Facebook channel.
Saints earned a return to the top table of European rugby by virtue of their fourth-place finish in the Gallagher Premiership.
They could lock horns with the likes of PRO14 champions Leinster or recently-crowned French kings Toulouse.
Chris Boyd’s side will find themselves in either Tier 2 or Tier 3, depending on the results of a preliminary draw.
Clubs involved in the draw are...
Gallagher Premiership Rugby: Saracens (Tier 1), Exeter Chiefs, Gloucester Rugby (Tier 2), Saints, Harlequins (Tier 3), Bath Rugby (Tier 4), Sale Sharks (Tier 4)
