Assistant referee Matthew Wilkes was unmoved by Newcastle appeals that a goal should have been awarded.
Pardew felt his side had been robbed of a goal but Reid, who signed a new contract at Upton Park earlier in the week, was adamant he had cleared in time.
Winston Reid: "No, it was not in.
"I am dead honest and I know it wasn't in. My foot was actually on the line and I got the ball away in time, which was good.
"As a defender you are trying to save goals and, fortunately enough, we came off at the end having not conceded any."
