The defender pulled out of the Uruguay squad after having an operation to his leg to fix the damage from the Roma midfielder's dangerous tackle
Porto has confirmed defender Maxi Pereira was forced to undergo surgery after being injured by a Daniele De Rossi challenge in Tuesday's Champions League playoff clash with Roma.
De Rossi was issued a straight red card after catching the 32-year-old on his shin when attempting to charge down a clearance during the first half of Porto's 3-0 victory at the Stadio Olimpico.
Pereira, who was pictured leaving the stadium on crutches, was consequently forced to withdraw from Uruguay's squad for the World Cup qualifiers against Argentina and Paraguay next month, with Jorge Fucile called up as his replacement.
