Murphy's red card was more of an injustice than Stephens. He slipped and brought the man down, it wasn't even a tackle, but still didn't get overturned.
Calde's red card was after a 50/50 challenge & the bloke broke his leg.
We've appealed there or four red cards in recent years without any further suspensions.
It's worth a try, but I don't think it will be overturned.
