The Galaxy will host Colorado in a US Open Cup play-in match on May 27 at HDC. The game is one of two the Galaxy must win in order to reach the tournament proper.
May 27 is the night before US-England so it is doubtful that the Galaxy would have David Beckham and Landon Donovan available. The Galaxy won both of its USOC play-in matches a year ago, including a dramatic 3-1 extra-time win over New York at HDC last year.
