LOS ANGELES - David Beckham could miss the rest of the Los Angeles Galaxy's season after being diagnosed with a sprained right knee Thursday.
The English midfielder underwent an MRI exam that confirmed he sprained the medial collateral ligament, the team said.
Beckham, 32, was injured in a tackle with Pachuca midfielder Fernando Salazar in the first half of Wednesday night's SuperLiga title match. The Galaxy lost 4-3 on penalty kicks.
He was expected to be out about six weeks. That would place his return at mid-October, with the Galaxy having three regular-season games left - against Toronto FC on Oct. 13, New York on Oct. 18 and at Chicago on Oct. 21.
'It's just gone from one thing to another thing,' Beckham said Wednesday night. 'Maybe it's time for me to just say, 'I need the rest,' and get it right and don't come back until it's right.'
He already had been nursing a left ankle injury that caused him to miss seven games since joining the team July 13. The last-place Galaxy (3-10-5) are long shots top make the playoffs.
Beckham's latest injury also means he won't be joining England's national team. He had planned to fly to London on Sunday for 10 days with the team as it prepares to play Israel and Russia in two Euro 2008 qualifying games.
