Baines picked up knee and calf injuries during Saturday's loss to Southampton, the club's official web site reports.
Analysis:Baines will be assessed in the coming days, but manager Roberto Martinez said "it shouldn't be too bad." It's tough to take that without a grain of salt, as Martinez said after last weekend's match that Kevin Mirallas was suffering from cramps, only to find out his groin injury will keep him out for the rest of the season.
