Boss Dean Smith has a full-strength Walsall side to pick from against Chesterfield after Sam Mantom's return to action.
The midfielder had been out since August with a knee problem but came off the bench in Tuesday's 1-0 defeat at Crawley.
He also played an hour of the reserves' 2-0 win over Port Vale on Wednesday but is likely to start from the bench.
Five-goal top scorer Tom Bradshaw is also available after shrugging off a hamstring injury.
Chesterfield have no new problems and will add Oscar Gobern...
