The midfielder is one of two changes from Thursday's 3-0 away win against Queens Park Rangers at the expense of Jordan Clark who misses out with a slight knock.
The other change comes up front, with Elijah Adebayo fit again and in the starting line-up.
There is a welcome return to the matchday squad for defender Reece Burke, who has been ruled out with injury since the end of September. The centre-back is back on the bench, along with Casey Pettit as defensive options for the boss.
Luton Town: Horvath; Doughty, Bree, Lockyer, Potts (C), Bell; Watson, Campbell, Mpanzu; Adebayo, Morris.
Substitutes: Isted, Cornick, Berry, Woodrow, Burke, Jerome, Pettit.
Referee: Matt Donohue
