Sergio Aguero has undergone minor knee surgery, the Manchester City striker has announced.
Aguero has been troubled by a problem in his left knee for the past five weeks.
Last Friday City boss Pep Guardiola admitted he was unsure when the 29-year-old, who has scored 30 goals this season and 199 for the club in total, would be fit again.
Aguero has now had keyhole surgery in a bid to resolve the issue.

No timescale for his recovery has been given but, with City already crowned Premier League champions, the World Cup will be his main target.
Aguero has not started a game since City's victory over Chelsea on March 4, although he was an unused substitute against Basel on March 7.
The Argentina international tweeted: "Recovering from an arthroscopy on my knee. Fully motivated to get back soon to the field."

Following his lay-off he returned to action as a late substitute in the derby defeat to Manchester United on April 7, when he was hurt in a controversial challenge from Ashley Young that went unpunished.
After that he was unable to train fully in the build-up to the second leg of City's Champions League quarter-final against Liverpool on April 10. Again, he was only able to appear as a second-half substitute.
With the issue still bothering him he was ruled out of last Saturday's 3-1 win at Tottenham, with Guardiola casting doubt over whether the player would play again this season.
Guardiola said: "I don't know (when he will be fit). We cannot forget he was two months injured.
"He made a huge effort, because after the action from Ashley Young against United, with problems in the knee, he could not train. Afterwards he could not run.
"I don't know if he will be ready for Swansea (on April 22). Hopefully (he will be back) for the last games, if we need him, and especially for the World Cup."
