Alonso sat out Wanderers' 1-1 midweek draw against Derby as he served a one-match ban for his red card against Nottingham Forest last weekend.
Sam Ricketts is expected to make way for the Spaniard at left-back, while boss Dougie Freedman could shuffle his options in attack once again after conceding Craig Davies and David Ngog appeared jaded during the closing stages at Pride Park.
Ngog remains at the centre of transfer speculation concerning a possible move to Dynamo Kiev, despite assurances offered by one of his representatives, and Marvin Sordell and Kevin Davies could return to lead the line.
Midfielder Keith Andrews (thigh/Achilles) remains a doubt, while defender Matt Mills is stepping up his rehabilitation from a thigh problem.
