Scotland, who arrived last month on a short-term deal until the end of the season, has stepped off the substitutes' bench to score Barnsley's winner in each of his first three matches and manager David Flitcroft could be ready to reward him.
Scott Wiseman is Flitcroft's only new injury concern after the defender picked up a knock in training that has left him doubtful.
Barnsley have dropped only two points in their last five league games as they bid to beat the drop, but Flitcroft could be tempted to make one or two changes.
Striker Chris O'Grady, on loan from Sheffield Wednesday, is pushing for his first start, while the likes of midfield pair Tomasz Cywka and Jacob Mellis, defender Bobby Hassell, plus youngsters Reuben Noble-Lazarus and Danny Rose could all come into contention.
Midfielder Stephen Dawson (ankle ligaments) and defender Jim McNulty (hamstring) remain sidelined.
