The Uruguay Football Association announced that 27-year-old Suarez had undergone minor knee surgery, suggesting he damaged the meniscus in Liverpool's final match of the season against Newcastle.
Suarez's arthroscopic surgery lasted about 30 minutes and he is likely to be sidelined for at least a couple of weeks but Uruguay officials remain confident he will be fit for the World Cup. Uruguay's first match is against Costa Rica on June 15 before they face England in Sao Paolo on June 19.
The assurances were not enough to prevent a furious reaction from several Uruguay supporters on Twitter, including menacing warnings for 22-year-old full-back Dummett, who collided with Suarez towards the end of Liverpool's victory at Anfield.
Dummett was sent off after catching Suarez in what looked an accidental collision, and his red card was later rescinded.

One Twitter user, Federico Gonzalez, posting on @FicoGonzalez13, wrote: "Hi @PaulDummett, from Uruguay we hope someday u come here to have a nice time w/ friends. We have things for you, like a bullet in the head."
Obviously a bullet in Federico Gonzalez wouldn't do much damage, unless it hit the ONE brain cell the wanker has between his lugs!
