All the stuff we've had in the past 45 minutes, what kind of indication has that given us for what we'll have for the next 35 minutes?

Philip Whitehurst: totally ridiculous sin bin.... May as well play touch rugby.....
Callum Thompson: That's a mad decision against Elliot Minchella. It's a penalty at best. We're sanitising the game.
Where do you stand on Eliott Minchella's sin binning? Let us know using #bbcrl on social media.

We have seen inside the Hull KR dressing room at the break.
Coach Willie Peters has his players gathered around him. Surely his message will be to cut out the indiscipline that has held them back.
