Revolution midfielder Stephen McCarthy underwent surgery on his left shoulder Monday. He will miss the rest of the season.
The surgery, described by the team as successful, was to repair a labrum in McCarthy's shoulder. He suffered the initial injury on May 21 and subsequently re-injured it three times, most recently in a September 4 training session.
In 21 games, the 23-year-old scored two goals and made an assist. He is expected to make a full recovery and be ready for the 2012 preseason.
COLUMBUS, Ohio - Ola Kamara scored his 14th and 15th goals of the season and the Columbus Crew beat the New England Revolution 2-0 on Sunday night to keep their playoff hopes alive.
Columbus (7-11-11), which played in the 2015 MLS Cup, is ninth in the Eastern Conference, but only five points behind D.C. United for the final playoff spot. New England (9-13-9) is seventh, one point back.
In the 42nd minute, Kamara slid a shot through the legs of defender Darrius Barnes and it got past a diving Brad Knighton. Kamara added a penalty-kick goal in the 84th after he was nudged from behind by London Woodberry.
Kamara has scored five times in the last three games and leads all MLS newcomers for goals scored this season. He trails New York's Bradley Wright-Phillips by five goals for the MLS Golden Boot.
Revolution forward Kei Kamara made his return to Mapfre Stadium after being traded from the Crew in May.
MONTREAL - Kai Kamara scored in the first minute and Kelyn Rowe added two goals to help the New England Revolution beat the Montreal Impact 3-1 on Saturday night.
The Revolution (9-12-9), who lost to Dallas in the U.S. Open Cup final this week, posted a third straight win in Major League Soccer play with only their second road victory of the season. New England moved two points behind fifth-place Montreal in the Eastern Conference playoff race.
Didier Drogba scored on a penalty for Montreal (9-9-4), which has only one win in seven games. Perhaps more alarmingly, the Impact are 0-3-1 and have conceded 11 goals in their last four home games.
