Dean took charge of a 2-2 draw between the sides in 2009 and was struck by a coin thrown from the Cardiff section of the crowd before half-time.
He went on to award Cardiff a controversial stoppage-time penalty from which Ross McCormack equalised.
Roberto Martinez, then the Swansea manager, said after that game: ''Mike said the penalty was given because Ashley (Williams, Swansea defender) had his arms around the striker (McCormack) but there were nine or 10 instances like that in the game. It was an emotional decision.''
Dean has not taken charge of a Cardiff home game since.
FA rules forbid managers from talking about an official ahead of a game, with a video guide to media comments misconduct on the governing body's website stating disciplinary charges may be brought for "any comment about an appointed match official prior to the game".
Neither manager was critical of Dean, but both chose to speak about his appointment.
When asked if he was surprised to see Dean had been placed in charge of the game Mackay said: ''No. He is a top-level referee.
''There have been plenty of occasions where a referee has been involved in something and then a couple of years later has gone back into the same environment. It is probably good that that happens. He is a very good referee.''
During his pre-match press conference, Laudrup had added: "I don't know if I am surprised.
"He will be the referee, he will do his best. Firstly, because he is a professional and secondly because he will have a lot of eyes on him at the stadium, on the television, from the FA, the referees' association, everybody will look at him for his performance. I am confident he will deliver his best."
