The striker from Seville, Brazil, will most likely not play this season and will have to miss next year's World Championship in Germany. This diagnosis was revealed after conducting detailed examinations of the player's knee.
The tests performed on Tuesday confirmed that the Brazilian national team striker had torn his right knee cruciate ligaments. The club's medical staff stated that the 25-year-old striker will undergo surgery this week, and the rehabilitation period will be six months, not four as previously thought.
R. Oliveira, who was the top scorer for "Betis" last season with 22 goals, suffered the injury in a match against London's "Chelsea" at the beginning of November, which Sevilla unexpectedly won 1-0 at home.
In one episode of the match, the Brazilian clashed with Portugal's defender Ricardo Carvalho while fighting for the ball. After this incident, the player was carried off the field on a stretcher. It is worth mentioning that the referee did not notice any foul on Portugal in that episode.
R. Oliveira was a member of the Brazilian national team, which won the Copa America in 2004 and the Confederations Cup in 2005.
