The four clubs battling for survival in the Betfred Super League will all kick-off their matches 7.45pm on Friday.
Wakefield Trinity, Huddersfield Giants, Hull Kingston Rovers and London Broncos, who all have 20 points, will know their fate around 9.20pm - and don't rule out golden point coming into operation.
Trinity’s game at home to the Broncos will be televised, with Huddersfield’s match against the Catalans Dragons and the Robins’ trip to Salford likely to be featured prominently during the Sky broadcast.
London must win to ensure they survive given their inferior points difference, but will avoid the dreaded drop if they can overcome Wakefield.
Sky have also confirmed that Wigan’s home game at Castleford will be Thursday’s televised game.
Leeds’ home game with Warrington will also take place on Friday, as will Hull FC’s game with Saints.
