I don't blame the ref for the head injury thing. He had no choice as even if he thought they were trying it on, the downside of being wrong is too serious. I do however think it was gamesmanship from them, and that it did slow our momentum and quiten the crowd and it was done for that exact purpose. It is naive to think otherwise. If his head injury had been as serious as their coaching staff were making out they wouldn't have sent him back on so quickly, and it was particularly galling to see him go straight into a defensive sprint when he re-entered the field, having apparently been out of it on the ground seconds earlier. They really must have used a 'magic' sponge.
On the penalty it was a farly clear one to me. Wilson knew it and didn't make much of a fuss about it either Not particularly blaming Wilson for it as his actions were instinctive, but he really would have been better looking to block rather than win the ball in that situation, as I think their player would have found it difficult to score from that position. That's exactly what the Huddersfield keeper did with the O'Hare situation, when O'Hare kicked it out of play waiting for the keepers challenge, which didn't come.
