It’s the Gers first cup match of the season after it was postponed due to the weather earlier this month.
Speaking to RangersTV ahead of the game, Reilly said: “I think it will be a really tough game, anything can happen in cup games.
“They have recruited a lot of players this year so we might not know their team but hopefully we will go in with the same mentality that we did on Sunday and come away with the points.
“Two of our games got postponed but now we are back so it will be good to get going and hopefully we can get a good start in the cup as well.
The new-look squad kicked off their SWPL league campaign on Sunday with a 3-0 victory over Hearts, and Reilly says there are positives and negatives the Gers can take from the game.
She continued: “It was really good to get going and to get a game under our belts as a team but hopefully we will kick on from here and keep developing.
“Obviously we have been training really hard but games are different to training so it was nice to see how we all play and work well together.
“It was really important, we have got a lot of pressure on us but I think we did really well.”
Thursday’s game kicks off at 8pm and fans can pay at the gate at Rangers Training Centre. Adults £5, Concessions/Students £3 and Children £1.
