The midfielder spent the past few days on the sidelines due to injury, but is set to make his comeback after returning to practice on Thursday
The Mali international picked up a calf injury in Barcelona's 4-0 win over Espanyol last weekend, and was taken off after 66 minutes of play to make way for Cesc Fabregas.
Keita was restricted to doing individual exercises in the past few days due to the knock, but the 32-year-old joined his team-mates for squad training again on Thursday.
It is not yet known whether the midfielder will feature at the weekend, but he is expected to at least make the match squad for the game in Seville.
Saturday's encounter at the Estadio Benito Villamarin kicks off at 22.00CET.
