If we beat Dewsbury, we're assured of third.
If we lose to Dewsbury and Oldham win their last two games at home to Workington on Wednesday and at home to Midland next Sunday, we will finish fourth behind Oldham.
Team 2 gets a bye in the first round of play-offs. Team 3 is at home to Team 4 with the winner away to team 2 the following week. The winner of that match is at home in the play-off final.
