Barnsley manager Mark Robins feels his players owe it to their fans to put Saturday's defeat at 10-man Reading behind them.
Robins cut a frustrated figure after his side failed to take advantage of Zurab Khizanishvili's 61st-minute dismissal in Saturday's 3-0 defeat.
Robins said: "We let our supporters down at the weekend. They travelled a long way and those are the people we play for.
"We have to put things to rest away from home before it becomes a major issue and we have a game coming up now quickly.
"We have to put it right on Tuesday. We have to learn from that and make sure that type of performance is a rarity to say the very least.
"We know what to expect from Scunthorpe and, first and foremost, we have to compete and match their effort and endeavour. You cannot underestimate them and we will be going there with a mentality to put it right."
