Lee Nguyen has undergone shoulder surgery after being the only member of the New England Revolution to play in all 30 games this season.

The midfielder had the operation on Monday to correct chronic instability in his right shoulder. In 27 starts in his first season with the Revolution, he had five goals and two assists.

The Revolution acquired him through the MLS waiver draft on March 2, one day after he was waived by the Vancouver Whitecaps.
