Vuckic saw more action for Toon in defeat at Liverpool.
Reflecting on Vuckic's performance, Pardew told the Evening Chronicle: "I thought Haris grew into the game.
"You'd expect that. It is at Anfield, and Liverpool have some great players, but we went toe-to-toe with them.
"Hatem was always going to be first choice to come on, but the game had perhaps gone away by then."
