The winner of this on is all but safe and the losing team in real peril.
Having said that, both of these sides have to play London on their own patch in the next few weeks so, there's still going to be something left in the relegation battle, even after this one.
Let's not forget Huddersfield either. They have Cas, followed by Hull FC and Saints away from home and whilst they have the relevant comfort of Catalan at home for their last game, they too could be in real danger.
