Both players were withdrawn in the second half against Nottingham Forest, striker Tudgay due to a tweaked back muscle and defender Wood as a precaution because of a slight groin strain.
Laws will be without Francis Jeffers, who sits out the last of a three-game ban, but fellow forwards Akpo Sodje and Leon Clarke will come into the reckoning.
Sodje, who has recovered from a groin injury, replaced Tudgay on Saturday and Clarke was on the bench after finally overcoming a hamstring problem.
Defender James O'Connor missed out against Forest due to a hamstring strain and remains doubtful while Laws must decide whether to recall Sean McAllister to his midfield or retain summer signing Tommy Miller in his starting line-up.
