Team A has two GCs in 1st half , after a couple of early warnings too, for physical tackles and captain is spoken to on 2nd one and asked to help tidy them up. Both teams therefore aware that tackles need to be cleaner and Team A do clean up their act until half time with no more cards or physical tackles. Team B throughout the half are impeccably behaved and do not get spoken to at all, about anything. In the 2nd half Team B get an early big blow and warning for a stick tackle / breakdown tackle from behind just outside the 23m area. 5 mins later, different player but same type of tackle made inside 23m. Big blow, PC and...................?? What else and why?
