Hatters boss Rob Edwards has made just one change to the whole squad, as forward Joe Taylor comes on the bench in place of Luke Freeman.
Alfie Doughty was a potential doubt for the Hatters after being subbed off with cramp before the end of the first leg, but keeps his place in the starting line-up.
On loan goalkeeper Ethan Horvath and forward Carlton Morris both start and make their 50th appearance for the club.
