SAO PAULO -- Brazil has called up Manchester United right back Rafael to replace the injured Dani Alves for upcoming friendlies.
Rafael was called up on Friday because Alves broke his collarbone while practicing with Barcelona earlier this week.
Brazil will play Denmark on May 26; the United States in Landover, Md., on May 30; Mexico in Arlington, Texas, on June 3; and Argentina in East Rutherford, N.J., on June 9.
The matches are part of Brazil's preparations for the Olympics, the only significant competition the five-time world champion has yet to win.
The Olympic tournament is played with under-23 teams, but each nation can use three over-age players.
