The midfielder saw red in the 71st minute of an action-packed game for what referee Mark Clattenburg clearly thought was a dangerous, over-the-top tackle, and Cork reacted as if he had been badly hurt.
Pulis said: "I've spoken to Mark about it and he's going to have a look at it and then take a view from there. You've got to be careful what you say. It's disappointing but you have to get on with it.
"I was disappointed with the reaction of the player. That didn't help. I'm a great advocate for players getting up and getting on with things and that (Cork's reaction) doesn't help referees.
"Whether the reaction of Cork, who is a good player and a good lad, has influenced Mark, I'm not sure, but Steven certainly doesn't stamp on the player. There was no intent. He's actually planted his leg between his legs, which was quite clever."
