The ref got there eventually and may have without the players pointing it out.
That sin bin was pretty critical. The ref was looking happy with the penalty. Our guys were quicker than him that it should be a sin bin.
Even if they didn't get him for a professional foul he didn't use his arms.
We managed that period quite well. Got over early when we had field position. Then didn't get carried away moving the ball against 12 men when we needed to get up the field.
