Cabaye defends Newcastle boss Pardew against boo-boys
Cabaye confirmed he was injured and unable to continue.
The France midfielder, who opened the scoring with a sublime free-kick, said: "The fans were very angry but they did not realise I needed to come off.
"It is unfair and they should not blame the manager, it was my decision. I was not fit enough to finish the game.
"I was afraid about my groin. I have come back from surgery and did not want to get pain again."
