The Uruguay international is yet to feature this term due to a hamstring injury that he suffered during the Copa America, but the centre-back was back on the bench against Borussia Dortmund in the Champions League on Wednesday night.
Araujo is now in line to start against Leganes, with Inigo Martinez expected to be the player to miss out, but that could be the only change to the side that took to the field for the first whistle against Dortmund.
There had been some concern surrounding Raphinha's fitness, with the Brazilian replaced in the 71st minute of the clash with BVB, but an injury for the in-form attacker has since been ruled out.
Frenkie de Jong and Gavi are both pushing to start, but it seems likely that Marc Casado will continue alongside Pedri in the middle, with Dani Olmo operating in the number 10 position.
Ferran Torres is in excellent form, scoring four times in his last three appearances, including a double off the bench against Dortmund to win it for Hansi Flick's side.
However, the Spaniard is again expected to be among the substitutes for the first whistle on Sunday night.
Ansu Fati and Andreas Christensen are also now back in full training, with the pair recovering from injuries, and it is possible that both could be included in the squad, but Marc-Andre ter Stegen and Marc Bernal are long-term absentees.
Barcelona possible starting lineup: Pena; Kounde, Araujo, Cubarsi, Balde; Casado, Pedri; Yamal, Olmo, Raphinha; Lewandowski
