With just two regular season games left in the Betfred Super League the final line-up for the Super 8s will soon be completed.
Leigh and Widnes already know they will be competing in The Qualifiers as they look to battle for a place in the top flight, while Catalan are almost certain to join them.
Warrington travel to Wigan on Thursday having given themselves a chance of finishing in the top eight with two wins in their last three matches, but their fortunes depend on Huddersfield’s results.
The Giants are three points above Warrington and a victory for them against Leigh on Friday would consign the Wolves to a place in the Middle 8s.
St Helens host Catalan on Sunday aiming for a top four spot (St Helens 1/5, draw 33/1, Catalans 7/2 – match odds).
Saints are sixth in the table at present and a win could move them to within two points of fourth-placed Hull FC.
Elsewhere on Friday, Castleford Tigers will do battle with Salford Red Devils at home, while Leeds will look to widen the gap between themselves and Ian Watson’s side.
The Rhinos face Hull FC at Headingley and a win could see them move even further away from fifth-placed Wakefield Trinity.
Chris Chester’s team will travel to Widnes knowing a win could see them move up to third if results go their way (Widnes 11/8, draw 22/1, Wakefield 8/13 – match odds).
