Diego Costa has left hospital after he underwent successful surgery on a neck injury, Atletico Madrid have confirmed.
Atletico said this week that the striker had gone under the knife after tests found he had suffered a cervical disk herniation.
Brazil-born Spain international Costa was discharged on Friday after his operation but is expected to be out of action for up to three months.
"The functional recovery period is to begin after a few days of rest," said a short Atletico statement.
Costa has scored twice in 15 appearances in all competitions this term, having struggled to match the initial impact of new signing Joao Felix or the recent form of Alvaro Morata.
Atleti, one point off the top of LaLiga in third place, are away to Granada on Saturday.
B-team striker Dario Poveda is part of the 18-man squad for the match and could make his first senior appearance for Diego Simeone's side.
