the ball never touched the ground or an opposition player before robinson batted it back towards his own line. no knock on

Nine times out of ten, Robinson's dropped ball would have been a knock on. The Leigh camera was in the East stand, where the 'incident' occurred and, in all honesty, it looked a knock-on to me. Anyway, as Duffy says, he doesn't think it influenced the final result. Halifax got on a roll, after that, and were out of sight, before we got a sniff in again.

What happened to the yellow card for deliberate obstruction ?

wasn't given but it should've been

Gareth Hewer clearly asked his t/j for help, and was badly advised. I thought Hewer had a poor game all round. That said, I will freely admit that the better team won, on the day.
