The Italian club worked out a deal with the Los Angeles Galaxy that allows the 33-year-old Beckham to forgo his expected return to the U.S. on Monday.
"I'm really grateful to the LA Galaxy and AC Milan for making this dream deal happen," Beckham said in a statement to the British network. "The perfect result for 2009 would be for me to help Milan to reach the Champions League and for the LA Galaxy to make the playoffs and win the MLS Cup."
Beckham has struggled since the Galaxy signed him Jan. 11, 2007. He has played in 30 games with five goals and 12 assists, and was not helped by a knee injury in his first season.
"We are hoping he comes back to help (Galaxy coach) Bruce (Arena) and his team win the MLS Championship.," said LA executive Tim Leiweke.
