Robert Lewandowski is a major doubt for the Copa del Rey final and the Champions League semifinal after Barcelona confirmed the striker has a hamstring injury.
Lewandowski, 36, was taken off in the second half of Saturday's 4-3 comeback win against Celta Vigo and underwent tests at the training ground on Sunday.
Barça have confirmed he has a hamstring injury, but have not revealed how long they expect him to be sidelined.
However, sources have told ESPN he is a major doubt for next Saturday's Copa final against Real Madrid in Sevilla.
