The Wakefield coach and former Wigan player, Tony Smith, will treat the match that could lift his old club off the foot of Super League as a cup final.
A fourth win in a row tonight, should it be by a 34-point margin, will not only take the Warriors out of last place, but also above Wakefield. "It will be like a cup final, but it won't mean the end of the season for either team," Smith said. "There will still be eight games left - all will be like cup finals."
Wakefield have Jamie Rooney back in their side, while Wigan have Wayne Godwin available after injury. For a third game in succession, though, there is no place for Pat Richards, whose future with Wigan looks doubtful.
Events at the foot of the table reduce the spotlight for once tonight on the meeting between Leeds and Bradford. The Rhinos have Danny McGuire back after resting a leg injury, but Matt Diskin is still not fit.
The Bulls hope to field Lesley Vainikolo, but include Andy Smith in their squad despite him going into spasm after a blow to the head at Salford last week.

The Huddersfield forward, Jon Grayshon, has returned to the club after two months on loan to Batley and goes straight into the squad for Sunday's game at Warrington.
