Nathan Jones' side will look to put defeat against Preston North End in their rear view mirror with a positive result against the Robins.
The opposition:
Bristol City are yet to find the winning formula in the Sky Bet Championship this season, with a single point to their name after the first three games.
They were forced to settle for a draw against Wigan Athletic at the weekend, after Andreas Weimann's early goal was cancelled out by Will Keane.
Weimann has scored in each of their four opening games including a late strike in the Carabao Cup win against Coventry City, eyeing an improvement on the 22 goals he managed last season.
Last time we met:
Tom Lockyer and Elijah Adebayo scored as the Hatters extended their home unbeaten run to four matches in all competitions with a 2-1 win over Bristol City in January.
Lockyer, back in the Town line-up for the first time since the Cardiff fixture in November, netted from a James Bree cross in the first half to put the Hatters ahead.
Andreas Weimann equalised for the away side before Adebayo scored his 12th goal of the season to put Town back in front, stabbing home from close range after another Bree cross.
