Manager Simon Grayson admits the performances from his substitutes on Saturday have given him food for thought ahead of Tuesday's game.
New signings Stevie May and Eoin Doyle came on in the second half and impressed their new manager, who believes they have a lot more to give over the course of the season.
"We knew when we brought them in that they were going to bring something to the team and that's why we brought them in.
"People may have wondered after the game on Saturday why we didn't start all three of the strikers but it's not that easy sometimes.
"What they have got is the energy and quality and they are hear for the long term not the short term and they are still settling into how we want to play etc.
"I am more than pleased with them and what they contributed, they were effective and I'm sure we will see many more sides of that."
And the manager will have to review his squad once again ahead of the game, with a number of players ruled out with injury at the weekend.
The likes of Paul Gallagher, Jordan Hugill and Kyel Reid were all unavailable, along with long term absentee Jermaine Beckford, but the gaffer hopes to see some of those players back sooner rather than later.
"We've not got the biggest of squads, which is something that we decided on but when you lose four players, with Jermaine out long term as well,
"The other three are probably not going to be too far away but whether they make Tuesday night is something we will have to look in to.
"But it's what we deal with, we need to be hard to beat and express ourselves, and play with the right tempo and hopefully get the three points come the end of the game."
