Manchester City boss Pep Guardiola says he is uncertain if Gabriel Jesus will play again this season.
The Brazil international suffered a fractured metatarsal during City's 2-0 Premier League win over Bournemouth last Monday and travelled to Barcelona for surgery.
"Last night he had an operation, it was good, really good," he told a news conference. "The most important thing now is a good recovery and he is going back when he will be fit, I don't know if it will be the end of the season or next season.
"Now to be calm, all our support to him and his family and waiting for when he is coming back."
Jesus' injury means Sergio Aguero is likely to regain his place as City's first-choice centre-forward, with the Argentina striker having been relegated to the substitutes' bench for the matches against West Ham, Crystal Palace and Bournemouth.
Aguero's future has been cast into doubt following Guardiola's decision to drop him but the manager has no doubts that he will perform well for the remainder of the season.
"I don't have doubts," he said. "He has to do what he has done since the beginning of his career. Nothing more.
"It's not easy for the player who does not play. Sergio was more than professional."
