Kingstonian could be without leading scorer Pelayo Pico Gomez for the foreseeable future.
Pico Gomez limped out of Tuesday’s 3-0 win at VCD Athletiic with a groin strain and is a major doubt for the weekend’s FA Cup clash.
But Williams believes Ks can still cope.
“Pelayo has been playing with a bit of a groin strain and it flared up again on Tuesday,” he said.
“He has to be a major doubt for the weekend and we don’t know how long he’ll be out.
“It is a blow because he has been playing very well and with confidence.
“We’ve still got some quality to come off the bench.”
