The 26-year-old defender seems certain to miss the rest of Valencia’s Champions League group stage games against Chelsea, Genk and Bayer Leverkusen. It is third in Group E.
Valencia doctor Jorge Candel says Maduro underwent surgery in the Netherlands, which stabilized the injury. Candel says the recovery time will be “longer than we thought” because the injury was “complicated.”
Maduro did not feature in either of the Netherlands’ Euro 2012 qualifying matches.
Fifth-place Valencia visits Mallorca in the Spanish league on Saturday and plays at Leverkusen on Wednesday.
