Lamine Yamal left Barcelona's win over Celta Vigo on Wednesday with an apparent hamstring injury, with club sources telling ESPN they fear he suffered a torn hamstring. The injury occurred immediately after he scored the game's lone goal from a penalty in the 40th minute and fell to the ground reaching for his left hamstring. Early estimates suggest a recovery period of at least five weeks, which raises serious concerns about his availability for Spain's World Cup campaign starting in June — the tournament is roughly 50 days away.
