"Hatem is a great player for us," said Pardew. "His application and his acceptance of the decision was spot on and he's growing as a person."
Pardew was quick to deny reports that Ben Arfa was unhappy or had been axed due to a lack of work-rate, and reiterated his happiness with the Frenchman's application in training and on the field.
"I don't think some of the things that are said about him are actually true," he added.
"He's been very good this week, accepted the decision, and he got his reward because he walked off as part of a winning team."
Ben Arfa has been at Newcastle since 2011 and had started each of his side's five previous fixtures in the Premier League this season.
