The Valiants are awaiting Football League clearance to add trialist Sean McAllister to the squad to travel to Southend.
Vale are missing five players through injury or suspension and are particularly hard hit in central midfield where Doug Loft, Sam Morsy and Darren Murphy are all unavailable.
McAllister, who has played and scored for Vale’s reserves this season is a free agent but Vale will need clearance from the Football League to sign him as the club remains in administration.
The club’s administrators Begsbies-Traynor have already sanctioned the move after discussions with potential owners Norman Smurthwaite and Paul Wildes.
