The 26 year old was a summer signing by Scott from Stevenage Borough, but has only featured once for the Milllers so far this season.
"Luke has not really been at a level physically to play at a standard I expect, He needs to go and play games. Luke is the sort of player that needs to be playing games to be match fit rather than doing it in training." Scott said
"But if you want to be match fit, you get yourself match fit. You can work in training, you can stay behind, you have days off, you can get yourself fit.
"Luke has not been in the side and that tells you everything you need to know." he added.
