Zola has been hampered by a hamstring injury in recent weeks and the problem resurfaced again against Aldershot on Tuesday night, forcing the striker off after 58 minutes.
Albion boss Gary Rowett will hope Billy Kee can recover from the knee knock that ruled him out in midweek. If Kee remains out and Zola is sidelined again, Matt Paterson could come into the starting line-up.
Leading scorer Jacques Maghoma also missed out against the Shots due to a knee injury sustained during last Saturday's 3-1 home win over Cheltenham and, like Kee, the winger will be assessed.
Paterson is joined by defenders Andrew Corbett and Marcus Holness and midfielders Jack Dyer, Jimmy Phillips and Chris Palmer in providing Rowett with options for changes.
