Clayton McDonald is an injury concern for Port Vale manager Micky Adams on his return to former club Sheffield United in the FA Cup.
McDonald was forced off after just 13 minutes of last weekend's 3-1 league win at Aldershot with a thigh problem.
His replacement in Hampshire, Liam Chilvers, is cup-tied so that possibly leaves an opening for either Gareth Owen or Joe Davis to return to the starting line-up.
Skipper Doug Loft (calf) could return to first team action after playing for the reserves this week.
Ahead of the second-round tie, Adams, a lifelong Blades fan and manager at Bramall Lane between December 2010 and May 2011, said: "United are a very good side, unbeaten at home so they will be favourites.
"But I have got good players who will relish a big match and playing in a big stadium."
