According to the BBC News, Beckham injured the internal lateral ligament of his right knee during a Madrid match. The player accidentally crashed into advertising boards while stretching to deliver a pass.
The sports star will undergo tests today to determine the extent of his injuries, and to learn if he will be able to play in the next match.
This summer, the star and his wife, Victoria Beckham, are planning to move to Los Angeles, where Beckham will join the Los Angeles Galaxy team.
Victoria Beckham, a former Spice Girl, will also be starring in her own television reality show on NBC, which will follow her new life in California.
