Uruguay striker Luis Suarez has injured his knee in training and could be a doubt for the World Cup, according to media reports in the country.
The 27-year-old Liverpool striker will have keyhole surgery on Thursday to repair damage to his meniscus, says Uruguayan broadcasters Tenfield.
Recovery normally takes between 15 and 20 days, adds the report. Uruguay play England on 19 June in Sao Paulo after their Group D opener against Costa Rica on 14 June.
Suarez finished as the Premier League leading scorer this season with 31 goals, despite missing the opening five matches through suspension.
