Barcelona's Robert Lewandowski was diagnosed with a hamstring injury on Sunday and is set to miss the Copa del Rey final and Champions League semifinal according to Spanish media reports.
The 36-year-old Polish forward, Barcelona's top goalscorer with 40 goals across all competitions, came off during his team's 4-3 LaLiga win over Celta Vigo on Saturday.
"Tests carried out on Sunday have confirmed that first-team player Robert Lewandowski has a semitendinosus injury in his left thigh," said Barcelona in a statement, without specifying how long he would be sidelined for.
Spanish media reported Lewandowski could be out for three weeks, meaning he would not be available next Saturday as Barcelona face Real Madrid in the Copa final in Seville.
The LaLiga leaders also host Inter Milan on April 30 in the Champions League semifinal first leg, and visit the Italians on May 6.
Lewandowski is set to miss league games against Mallorca on Tuesday and Valladolid on May 3, with a potential return against Real Madrid on May 11, a match which could decide the title race.
Barcelona, who won the Spanish Super Cup in January, are chasing a potential quadruple and are in the Champions League semifinals for the first time since 2019.
Coach Hansi Flick has used Ferran Torres through the middle as a replacement for Lewandowski before, and has also experimented with Dani Olmo operating as a false nine.
