The defender has missed his side's last two matches with a hamstring problem but he could be ready in time to play some part at the weekend.
Captain Andy Butler has a broken toe and will definitely miss out again.
Smith has no fresh injury or suspension problems and could be tempted to shuffle his pack.
The Saddlers, who sit eighth in the npower League One table, are unable to finish in the play-off positions following last Saturday's 1-1 draw with Bury and other results going against them.
This clash could be a good opportunity for Smith to give experience to some younger players.
