Liverpool will appeal the decision which meant they ended the game against Fulham with nine men, as they believe there is enough evidence to prove Mason made a mistake in showing Carragher a red card.
Television replays confirmed that Carragher got a toe to the ball when he tangled with Bobby Zamora, while the striker - who scored the first of Fulham's three goals - told Mason that Carragher had not committed a foul.
Mason, though, stuck to his guns and sent Carragher off for the first time in more than seven years but Liverpool's skipper is keeping his fingers crossed that the official will review his decision if he has another look at it.
'I felt it was wrong at the time and I have looked at it again since,' said Carragher. 'I just got my toe on the ball but the referee was behind us. It was maybe not the best position for him to be in.
'But it's always a giveaway when the player you are tackling gets up and says that you won the ball. I felt I had got it at the time and when Zamora got up and said the same thing, you don't need to say much else.
'The Fulham players came off at the end and said they didn't think it was a red card but it's just one of those things. Hopefully the referee will have a look at it for us and if he sees that I have won the ball, maybe he will change it.'
