I agree on the red card for DOGSO. It seems to me that Matt got a bit confused on whether the offence took place inside the area (yellow card) or outside (red), and once he had decided (correctly) that it was outside, perhaps with a bit of help from the AR on the far side, he forgot that a red card should then be shown. 1-2 baffling decision in the Championship, not least Gillett's award of a penalty to Watford (v Preston) which looked a clear dive.
