When you see the tape you'll see that the first red was the correct decision. Last man, made no effort to get the ball and clearly took the man out.
The "tackle" on Sparky in the first half should have seen them reduced to 9 men sooner. Then another Longball player threw a slap in the commotion.
How they managed to keep 9 men on the pitch is beyond me.
I hope they play as badly as that at the box next Friday.
