The Robins lost 2-0 to Reading in midweek and enter this game three points behind Barnsley, who have won back-to-back matches.
Tuesday's defeat against Reading proved to be the final straw as City parted company with boss Dean Holden after just six months in charge.
Not only have City lost six games in a row, five of those in the league, they have conceded 15 and scored only twice. Indeed, the Robins have failed to find the net in each of their last four games.
Barnsley followed up their impressive win against Brentford - ending the Bees' 22-match unbeaten league run in the process - with a 2-1 win against Blackburn Rovers in midweek.
The Tykes are now unbeaten in four league games, having previously drawn 2-2 with Cardiff City and 0-0 with Nottingham Forest.
In fact, since Valerien Ismael first took charge in October, only Norwich City (14), Brentford (13) and Swansea City (13) have won more Championship games than Barnsley (12).
However, Ismael's men are winless in 10 league meetings with Bristol City in a run stretching back to September 2012, six of those matches finishing all square.
Bristol City Championship form: WLLLLL
Bristol City form (all competitions): LLLLLL
Barnsley Championship form: LLDDWW
Barnsley form (all competitions): WDDLWW
Cauley Woodrow was preferred to Morris against Blackburn, but the latter scored again from the bench and is surely in Ismael's thoughts for a starting spot.
Meanwhile, midfielder Mowatt has been involved in six goals in his last 10 Championship matches - three goals and three assists.
Bristol City possible starting lineup:
Bentley; Mariappa, Kalas, Moore; Semenyo, Palmer, Lansbury, Nagy, Hunt; Wells, Diedhiou
Barnsley possible starting lineup:
Collins; Sibbick, Helik, Andersen; Brittain, Palmer, Mowatt, Styles; Chaplin, Adeboyejo; Morris
We say: Bristol City 0-1 Barnsley
Not since between December 2016 and January 2017 have Bristol City lost six league games in a row.
Against a Barnsley side back in form, and with a new manager not expected to be in place until after this match, we can see their losing streak continuing for a little while longer.
