Manager Kenny Jackett fielded a more settled side rather than opt for wholesale changes at half-time and Gary Alexander, Andy Frampton and Ryan Smith were all rested after picking up knocks during the 1-1 draw with Shelbourne on Monday.
Jackett also took the opportunity to evaluate trialists Charlie Daniels and Michael Daly, both of whom came on after half-time.
