"Somebody said I should ring the Guinness Book of Records. I am the only player to have been shown a yellow card for being grabbed by the throat," protested the incredulous Norway winger.
A moot point, as Wiley will argue he was booked for the tackle that prompted Mikel Arteta to lose his cool and spark a melee.
Blackburn team-mate Stephen Reid later denied he had been punched in the face, although it appeared that way from the stand, and Wiley kept his red card in his pocket.
Pedersen said: "If I get a yellow card then surely Arteta should get a red. I knew I was on four yellows so I tried to walk away. I was amazed he booked me."
Blackburn manager Mark Hughes, who loses Pedersen as well as Chris Samba and David Dunn at Arsenal on Saturday, said: "If you raise your hands, my understanding is that it's a straight red. I think he felt Morten clipped his shin and Arteta reacted. He probably should have gone. It was one of the decisions that mystified me."
