Newcastle United boss Alan Pardew has concerns over Yohan Cabaye's knee injury suffered in victory over QPR.

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."
