Hatters boss Nathan Jones has made three changes to the team that started the Sky Bet League Two game against Coventry last week as the Town set off on the road to Wembley in the Emirates FA Cup this afternoon with a home tie against Portsmouth.
Coming into the side to face the reigning League Two champions are Alan Sheehan, who returns after serving a one-match suspension last Saturday, and midfielders Pelly-Ruddock Mpanzu and Andrew Shinnie, who netted twice in the midweek Checkatrade Trophy win at AFC Wimbledon.
Glen Rea misses out as he serves a one-game ban following his late red card against Coventry, defender Johnny Mullins is sidelined by the ankle injury suffered in that defeat while Harry Cornick drops to the bench.
