Sevilla FC midfielder Renato could be out for a month after pulling a muscle in his left thigh during Thursday's 2-1 UEFA Cup defeat by FC Zenit St. Petersburg.
The 26-year-old Brazilian, who sustained the damage in the 15th minute of the game in Russia, is expected to miss Sevilla's remaining Group H matches against Vitória SC and Beşiktaş JK. Sevilla are third in the section, but have played a game less than leaders Zenit.
