Luis Suarez's knee injury may not be as bad as first feared, his mother has claimed
"The surgery is over and thank God everything went well. What Luis had wasn't as serious as we thought," she told the Associated Press news agency.
Meanwhile, Suarez' sister said the striker is set to face two-to-three weeks out after the surgery - which would mean a return just in time for the World Cup.
"The problem is that these days he won't be able to play, and will only be able to do physiotherapy," Giovanna Suarez said.
