On 13 February 2008, Ronaldo suffered a severe season-ending knee injury while jumping for a cross in Milan 1–1 draw with Livorno, and was stretchered off and taken to a hospital. The club confirmed after the match that Ronaldo had ruptured the kneecap ligament in his left knee. It marked the third such occurrence of this injury, which he suffered twice to his right knee in 1999 and 2000. Teammate Clarence Seedorf stated: "My heart stopped beating because it was like watching a repeat of the injury he suffered playing for Inter Milan against Lazio [in 2000]. His reaction was the same." Silvio Berlusconi told Italy's RAI TV: "He fears for his career. I called him last evening and told him to believe in himself. He has enormous physical potential." Ronaldo was released by Milan at the end of the season, as his contract expired and was not renewed.
