Sheffield Wednesday striker Gary Madine is hoping to shake off the effects of a dead leg.
Madine sustained the injury in Saturday's 2-1 win at Notts County and is doubtful as the Owls bid to climb back into an automatic promotion place.
If Madine fails a late fitness test manager Dave Jones will call on Chris O'Grady or Clinton Morrison to partner Ryan Lowe.
Defender Reda Johnson has missed the last four games with a hamstring injury and is not expected to return to contention until next weekend.
Jones has no other selection problems and is unlikely to make further changes but midfielder David Prutton and centre-half Miguel Llera are pushing for recalls.
Winger Jermaine Johnson remains sidelined with a long-term knee injury and midfielder John Bostock has been recalled by parent club Tottenham.
Walsall boss Dean Smith has no new injury or suspension problems ahead of the trip.
Smith watched his side take the lead at Yeovil on Saturday before going down 2-1, falling to their first defeat in seven games.
Emmanuel Ledesma came in for his second debut for the Saddlers at Huish Park, replacing George Bowerman, and changes are again expected to be kept to a minimum.
Richard Taundry (hamstring) hopes to return to first-team contention for Saturday's home clash against Stevenage while it remains to be seen when midfielder Adam Chambers (heel infection) will be back in the fold.
Walsall are just one point and one place above the drop zone, albeit with a game in hand, and face a tough ask against a Wednesday side who have won all three games under new boss Dave Jones.
However, they can take heart from their 2-1 injury-time triumph in the reverse fixture on Boxing Day.
