Pardew is hopeful key Cabaye did not suffer any lasting damage after finding himself on the wrong end of an X-rated tackle.
The Frenchman left the pitch on a stretcher after being felled by QPR midfielder Shaun Derry's 20th-minute challenge.
He said: "It was a strong challenge, but Shaun Derry is a player who makes strong challenges. The referee was right on top of it.
"I thought it was borderline yellow/red, but I think probably it was a yellow. He seemed to get the ball.
"There always controversy about tackling. It's very, very difficult for referees, so I am not going to sit here and criticise that decision.
"But Yohan was upset. He felt it was probably a little bit over-exuberant, but the doc thinks he is going to be okay."
