Scotland signed a permanent deal until the end of the season in time to be included following his release last week from Ipswich.
Tykes manager David Flitcroft could throw the 33-year-old straight into his starting line-up if Chris Dagnall fails to shake off injury.
Dagnall scored the winner in the weekend FA Cup win at Hull, but was stamped on in the process and is doubtful after being forced off soon after with a bruised foot.
Defenders Bobby Hassell and Scott Wiseman both sustained knocks at the KC Stadium and could face late fitness tests.
Flitcroft has no other new injury or suspension problems, but will still be without midfielder Stephen Dawson (ankle) and defender Jim McNulty (hamstring).
Barnsley, unbeaten in their last four matches, can climb out of the bottom three if they can secure their third straight home win.
