However, replays have shown that the contact was minimal from Carroll, with the Spanish defender seemingly making the most of the challenge.
"To be honest when I saw it first I didn't think he had caught him at all," Nolan told reporters. "I was quite surprised that he got the red card and I asked Howard Webb and he said that he had touched him, but what I have now seen on the replay, it is not good on Chico Flores's part.
"I think what will happen is that it will get rescinded. I think everyone who has seen it now agrees with that, even the opposition manager has said that it is not a red card. They have had their advantage, so I don't think he should be punished anymore.
"I think it should be rescinded, so we can have him back, so I'm hoping that they now do the right thing because if they don't it will be a travesty."
