Yeovil hope to have in-form goalkeeper Marek Stech available for their rearranged clash with North End.
The 23-year-old played a vital role in the Glovers' 1-0 win at Coventry on Saturday despite the fact his heavily-pregnant partner is still waiting to give birth.
And manager Gary Johnson hopes the arrival can wait until after Tuesday night's clash with North End.
"I have got every faith in (second choice goalkeeper and Glovers coach ) Gareth Stewart to be honest but we would like to keep the same team," he told the Western Gazette. "With any luck the little one will hold on a little longer."
Full-back Nathan Ralph, who has suffered with knee and ankle injuries since October, made a welcome return to the squad against the Sky Blues and he is set to be on the bench again while Joe Edwards will keep his place in the starting line-up.
The Glovers are only outside of the League One play-offs on goal difference.
Preston boss Graham Westley will be without suspended defender Bailey Wright for Tuesday's encounter.
The Australian centre-back will serve a one-match ban after he picked up two yellow cards in Saturday's 1-0 defeat at Colchester. Former Yeovil captain Paul Huntington will take his place in the starting line-up.
Westley is pleased to be able to call on Huntington for this clash.
He told the club's official website: "It is one of those fortunate things that we have lost a centre-half and we have gained a particularly motivated one for this occasion. It isn't a blessing in disguise, as we will miss Bailey, but we have good cover."
The Lilywhites will also be missing Stuart Beavon, Joel Byrom and Jack King, along with long-term absentees John Mousinho (hamstring) and Scott Laird (broken leg).
Keith Keane will maintain his place on the bench after recovering from injury.
