David Beckham has been fined $1,000 (£600) by Major League Soccer (MLS) following his confrontation with a fan during a friendly against AC Milan.
Beckham angered some fans of his LA Galaxy team by missing part of the MLS season while on loan at Milan, and was booed during the game.
At half-time, he approached one group of fans and appeared to challenge them to meet him on the pitch.
