I think it was more a case of just before the sending off, a truly blatant push and some holding of one of our players was seen by everyone, yet went unpunished and ignored by the Ref.
Follow that up a few seconds later with a legit ball-winning challenge that ended up in a sending off, you can see the cause of the frustration.
From where I was stood directly opposite, Carby won the ball and had it in his possession, before the Cambridge fella fell on him.
Pretty much what all the Cambridge players did all night.
Still, it's done now.
Big, BIG game this saturday.
Really would like a decent FA Cup run this year
