Doumbe is in line for a first-team return as on-loan Manchester
The club's other right back, David McNamee, is suspended and so Doumbe is set to get the nod.
On-loan Blackburn Rovers forward Paul Gallagher has been given the all-clear after a scan on his knee and comes back into contention along with Belgium international forward Emile Mpenza.
Bristol City boss Gary Johnson has a near full strength squad to choose from.
Jamie McCombe is the only definite absentee for the Robins, who have had a 10-day break since drawing 2-2 with league leaders Wolves at Ashton Gate earlier this month.
The defender is expected to return in mid-February after undergoing a successful operation on his stomach and pelvis last week.
Johnson insists the game at Home Park is the start of an important period for his side, he said: "The next five or six matches are vital to our season. We want to be competing in and around the play-offs and we need to put a run together to be able to do that.
"Having a largely fully fit squad is going to be important and we have used the break well in my opinion and the lads have trained well and look ready to go."
