The battle for the Betfred Championship title steps up another notch when the competition's new play-offs system gets underway this weekend.
Midlands Hurricanes (8th) host Whitehaven (9th) on Saturday and Sheffield Eagles (7th) do likewise with Batley Bulldogs (10th) the following day in straight elimination ties.
All those clubs see their season on the line this weekend but others in action get two stabs at making the latter stages of the play-offs in a five-week series culminating with the Grand Final.
Oldham (3rd) entertain Widnes Vikings (5th) and Doncaster (4th) welcome Barrow Raiders (6th) in Sunday's Qualifying Semi-Finals.
The winners of those two ties go through to Week Two where League Leaders Shield winners London Broncos and second-placed Newcastle Thunder come into the mix.
London will host the highest ranked qualifying semi-final winner with Newcastle welcoming the other Qualifying Semi-Final victor.
In the Winners Elimination Finals, the highest-ranked qualifying semi-final losers will be visited by the lowest-ranked elimination winners and, similarly, the lowest ranked semi-final losers will tackle the lowest-ranked elimination winners.
In Week Four, the preliminary finals see the highest-ranked qualifying final winners v the lowest ranked sudden death play-off winners and the lowest-ranked qualifying final winners v the highest-ranked sudden-death play-off winners for places in the Grand Final.
