Williams (groin) was ruled out of the 1-0 home win over Southend last weekend, when fit-again striker Dean Bowditch scored the winner seven minutes after his 70th minute introduction.
With Gavin Tomlin also fit - and featuring as a substitute against Southend - Yeovil manager Terry Skiverton is set to have a handful of strikers ready for selection.
The Glovers boss has also been boosted by the return from injury of central defender Stefan Stam, who made his comeback last week.
Central defender Terrell Forbes (illness) and on-loan Swansea midfielder Shaun MacDonald (thigh) are set to be fit for the meeting with Phil Parkinson's men.
