Manny Smith will be suspended for Walsall.
The centre-back was harshly shown red in last weekend's 4-2 defeat at relegation rivals Exeter, a decision which changed the pattern of the game, and will now serve a one-match suspension.
Olly Lancashire will step in for Smith while right-back Lee Beevers returns from his one-match ban served at St James Park to challenge Richard Taundry for a defensive start.
Young striker George Bowerman, 20, and midfielder Adam Chambers are both back in training after respective foot and calf injuries.
Walsall know victory against the Terriers in their final home game of the season will secure their League One survival, otherwise it will go down to a nerve-wracking final day for the second campaign in succession.
Huddersfield are again expected to be without striker Alan Lee.
Lee has almost shaken off the knee injury that has kept him out of the last two matches but is not expected to be rushed back ahead of the play-offs, so Lee Novak looks set to continue alongside Jordan Rhodes.
But the Terriers could be boosted by the return of midfield pair Oscar Gobern and Damien Johnson.
Gobern has missed the last 11 matches with a hamstring injury, while Johnson has played no part in the previous nine due to a similar problem. Both players came through unscathed in a behind-closed-doors friendly in midweek.
Goalkeeper Alex Smithies is back in contention after sustaining a head injury in training a fortnight ago, but manager Simon Grayson is likely to continue with Ian Bennett.
Defender Gary Naysmith remains sidelined with a knee injury as Grayson's side look to recover some form as they prepare themselves for the play-offs.
