The Hammers were held to a 1-1 draw by the Championship side in the initial tie earlier this month on what turned into a costly afternoon for David Moyes as both Jarrod Bowen and Lucas Paqueta limped off injured.
Michail Antonio is already sidelined with a knee problem, while Mohammed Kudus is away at the Africa Cup of Nations.
"The game tomorrow, Lucas Paqueta is not available and the same for Jarrod Bowen," assistant boss Billy McKinlay said on Monday morning. "They got injuries in the last game and we'll determine their availability for future games after tomorrow.
"We're short a couple of players so we'll have to make some changes."
Centre-back Konstantinos Mavropanos was forced off with a rib problem in the same game but is fit, while youngster Callum Marshall could be involved in Moyes’s first-team squad.
