CARSON, Calif. (AP) — LA Galaxy defender Robbie Rogers will be sidelined for at least six weeks after undergoing arthroscopic surgery on his ankle.

The Galaxy announced the injury Tuesday.

Rogers has been a mainstay on the Galaxy's back line for the past three seasons since changing positions from midfield to defense. He has started 10 games and appeared in 12 this season.

On his Instagram account, Rogers expressed regret that he won't be able to play Wednesday against Colorado on the Galaxy's annual Pride Night at StubHub Center.

Rogers became the first openly gay male athlete in a major North American pro sport when he joined the Galaxy in 2013. He scored his first goal for the Galaxy on Pride Night last season.
