Costa, who did not train with his teammates on Tuesday, had suffered a left leg injury in the quarter-final match against Sporting Lisbon on April 12 and was sidelined during the La Liga matches against Levante, Real Sociedad and Real Betis, reports Efe.
However, the Spain forward has been included in the list, along with the rest of the available first squad members and three players from Atletico B: goalkeeper Alex Dos Santos, defender Sergio Gonzalez and midfielder Roberto Olabe.
Both Juanfran Torres, who sustained a hamstring injury during Sunday's game against Real Betis, and Filipe Luis, who is still recovering from his injury, were not included in the list.
Atletico is set to be hosted by Arsenal at the Emirates Stadium on Thursday.
