Barcelona have announced goalkeeper Marc-Andre ter Stegen will undergo surgery on the patella tendon in his right knee on Tuesday.
The Germany international is to be operated on by doctor Ramon Cugat, with the club describing it as a "proactive measure" in a short statement released on their website.
Ter Stegen played in 46 games for Barca in the 2019-20 season – including 36 in LaLiga – despite having problems with the tendon during the campaign.
He was in goal for the humiliating 8-2 Champions League loss to Bayern Munich last week that ended Barca's hopes of European glory, as well as the tenure of head coach Quique Setien.
It is unclear how long the 28-year-old will require to recover; the LaLiga side are set to provide further information once the procedure has taken place.
News of Ter Stegen's situation was released not long after the departure of Setien was officially confirmed, while Barca also announced on Monday that presidential elections have been moved forward to March 2021.
Josep Maria Bartomeu is the current president but has come under heavy pressure following problems both on and off the field, including missing out in the league title race to rivals Real Madrid.
Concerns have also been raised over the club's business in the transfer market, as a number of high-profile signings have failed to impress following big-money moves to Camp Nou.
"The board understand that an immediate call for elections is not feasible, given that the league season will begin on the weekend of September 12, 2020 and the situation arising from the COVID-19 crisis – both economically and socially," a statement read.
"Consequently, the club will continue to implement the plan to reverse the sporting and economic situation, based on profound changes to the first team, plus a redefined budget to deal with the new situation caused by COVID-19, before the end of the current mandate.
"The holding of the elections from March 15 next year implies that the board of directors assume full responsibility regarding the 2020-2021 financial year.
"Likewise, the holding of elections on the first available date within the deadline set due to the end of the mandate, in accordance with the provisions of the club statutes, will allow an orderly transition to the winning candidacy, which will have a sufficient time frame in which to plan for the 2021-2022 season."
