Goals from Papiss Cisse (2) and Hatem Ben Arfa gave the Magpies a 3-0 lead before Shane Long's second half consolation effort.
But Hodgson's main worry will now be Morrison after he limped out of the action with a knee ligament injury.
Albion had to finish the game with 10 men as they had already used their three substitutes.
Hodgson said: "It's knee ligament damage. He will have the scan tomorrow and we will see what brings.
"The initial prognosis from the medical team is not good. We have to see what ligaments in the knee have been affected."
