Cardiff City manager Mark Hudson said:
"I think in the first half we weren't at the level we were last week. We started the second half really well and scored a goal which was disallowed.
"I'm still trying to work it out. I've watched it back over and over again. He's onside, they've given it offside because of a rule that the defender isn't in control of the ball but my argument to that is that Robbo [Robinson] was onside throughout that.
"I've spoken to Bobby [Madley]. He says he gave offside because of an action that is a defender not being in control of the ball but the main point is he [Robinson] is not offside at any point in the move.
"That's disappointing but, overall, we didn't work the keeper enough.
