French side Pia booked their place in Monday's fourth-round draw for the Challenge Cup after a 42-18 away win over Blackpool.
Toulouse went down 54-28 to York City Knights, while Limoux were defeated 38-22 by Gateshead.
Lokomotiv Moscow were easily beaten 60-20 by Swinton.
The draw, which will see the Super League sides enter the competition, will be made at 1930 GMT on BBC Radio Five Live.
Castleford, who were relegated from the Super League last season, were comfortable 88-10 winners over neighbours Castleford Lock Lane while Widnes easily overcame Normanton Knights 78-8.
A late try from Kevin Crouthers, converted by Francis Maloney, helped Dewsbury Rams claim a dramatic 36-34 win over Leigh Centurions.
The Rams trailed 34-24 with just seven minutes remaining but Josh Weedon crossed to bring them back into contention before the late drama.
Leigh's Adam Hughes then missed a late penalty which would have taken the game to extra time.
In another all-National League 1 tie, Whitehaven saw off Doncaster 24-10 with two tries from ex-Castleford man Richard Fletcher while Carl Sice also touched down on his 100th appearance for the club.
