Derek Adams' side travel to Blundell Park on Tuesday evening to face a Grimsby Town side who have lost just one in their last 10 fixtures.
The Mariners snatched a late victory over promotion chasing Bolton Wanderers on Saturday afternoon, substitute Ira Jackson Jr scored the winning goal on 84 minutes to secure a 2-1 victory for Paul Hurst's side.
The Grimsby victory saw the Shrimps close the gap to a single point between themselves and Bolton Wanderers with a 4-3 victory over Oldham Athletic.
Adams said: "Grimsby have come off a fabulous win against Bolton, they're fighting for their lives at the bottom of the Football League.
"We know at this stage of the season that no game is easy but we have just had two very good victories against Scunthorpe and Oldham, scoring four goals in each game.
"We just have to keep on fighting to continue that run. The players are hungry for more success and although we know that Blundell Park is a difficult place to go to, we went there earlier in the season and won.
"Picking up points at this stage of the season is vital because every point means something to us. We made it to 69 points on Saturday and we want to be on 72 by Tuesday night.
"We know it will be difficult, points in this league don't come easy and Grimsby will be in good spirits after beating a side in the automatic promotion places on Saturday.
"They're on a good run but our players are in very good form themselves, they're in a very good mood and we'll just keep on going."
