Ahmet Brkovic should be fit enough to feature after missing last week's goalless draw at Layer Road, but Perrett is still out with a groin strain. Paul Hughes probably won't feature either.
However, the good news for Hatters fans is that Ian Sharps and captain Jason McAteer are likely to be unavailable. Sharps missed the LDV Vans clash with Oldham midweek, and McAteer is suffering from a hamstring injury.
