Lee Canoville and Steve Woods are the only injury doubts for Leroy Rosenior as United build up to their second home game in as many weeks.
Canoville, who missed last week's 4-1 win over Macclesfield, has done a little light training this week. As has fellow defender Woods, who picked up a slight strain during the game.
Rosenior is likely to stick with David Graham and Jo Kuffour up front for the match, and United's fans will be hoping that the Gulls can break their Scunthorpe curse, which has seen the Iron dominate in games between the two teams over the last couple of seasons.
Iron manager Brian Laws is hoping to rush back 20-year-old defender Andy Butler, who has missed their last five matches with a bruised ankle. But Laws will be without the free-scoring youngster Steve MacLean, who is on loan from Rangers, and who scored 17 goals before Christmas. Remarkably though, he hasn't scored in his last eleven games.
Exeter City travel to Norfolk for their fourth round FA Trophy tie with King's Lynn on Saturday.
There are 32 clubs left in the competition, and Grecians boss Eamonn Dolan has put it on record that he wants to go all the way so that City's season can be remembered as an honour-winning one.
Steve Flack and Sean Devine are both doubtful, but youngster Sean Canham did well last week partnering James Coppinger up front.
Meanwhile, City's youth boss Mike Radford is going to be casting an eye over the youngsters released by the Gulls following their decision to close down their Centre of Excellence.
United chairman took the decision, with the full backing of head coach Leroy Rosenior, and hopes that the move will divert an extra £100,000 a year to the first team.
Plymouth Argyle will be live on Sky Sports this Saturday when they take on Brighton and Hove Albion at 5.35pm.
Midfielder Tony Capaldi is doubtful after picking up a knee injury while playing for the reserves and wasn't able to train on Thursday. So Paul Sturrock is likely to keep the same line-up as last week. Though Paul Wotton is pushing for a starting place, maybe in midfield in place of Lee Hodges.
Both Romain Larrieu and Jason Bent have begun training again, and Sturrock is likely to have a big decision to make soon over who is going to be his first choice keeper.
Youngster Luke McCormick has kept seven consecutive clean sheets, which is a massive achievement.
