England international Morgan's return sees Sione Kalamafoni move across from number eight to blindside flank for the game against their rivals.
Meanwhile, featuring in a Gloucester squad for the first time, is All Black scrum-half Jimmy Cowan. He is named amongst the replacements.
Boss Nigel Davies has admitted that he feels that there are certain similarities between the teams, but that Gloucester are ready for the encounter.
"I think we're very similar to Bath at the moment. We're both teams in transition with new coaching groups, new philosophies and new look teams," he said.
"We're both working hard to put those systems and philosophies in place, so it'll be interesting to see which side comes out on top on Saturday.
"It's important to keep the momentum going. We're at home and we desperately want to win and put in a big performance.
"This group of players are playing with lots of confidence at the moment, with lots of belief. We're ready for this fixture, it's a huge fixture."
Meanwhile, Sam Vesty will come into the starting line-up at inside centre for Bath as the West Country outfit look to clinch a vital win in the league.
This will be Vesty's first start of the season, and he will partner Dan Hipkiss in the midfield, with Michael Claassens and Stephen Donald forming the half-backs.
Having played at inside centre last Saturday in the win over Sale Sharks, Donald slots back into his preferred role of fly-half, replacing Olly Barkley, who last week played his final game for Bath before taking up a contract at Racing Metro 92.
The back-three does not change, with Kyle Eastmond and Tom Biggs out wide and Nick Abendanon at full-back.
Up front, Paul James is retained at loosehead, and will link up with Lee Mears - who is handed the captain's armband - and Davey Wilson to form an all-international front-row. In the absence of Club captain Stuart Hooper, who sadly injured his hamstring last Saturday, Dominic Day partners former Cherry and White Dave Attwood in the engine room.
"Kingsholm was once home to me and it is a special place. To be arriving there this weekend with my Bath teammates is a real honour. These are special days and there is a huge amount of history to remember as you run out. I can't wait for the game," said Attwood.
The back-row remains unchanged as Carl Fearns and Ben Skirving pack down on the flanks, with 66 times capped Scot Simon Taylor at number eight.
