United's De Rosario likely out for rest of season

D.C. United captain and reigning MLS MVP Dwayne De Rosario sustained a knee injury Tuesday that could sideline him for the rest of the season, his club announced Thursday.

De Rosario, 34, suffered a Grade 3 sprain to the medial collateral ligament in his knee while on international duty for Canada. He will be out 10 to 12 weeks and the regular season ends in late October.

A midfielder or forward, De Rosario has seven goals and ranks second in the league with 12 assists this season in 26 games. In just 44 games for D.C., he has 20 goals and 19 assists.

"DeRo is our captain, a great player and impossible to replace," United coach Ben Olsen said.

De Rosario was injured in a 2-0 defeat to Panama in 2014 World Cup qualifying. He scored the game-winner in a 1-0 win over Panama on Friday.

United is sixth in the Eastern Conference, one point behind the Columbus Crew for fifth place and a playoff berth. D.C. hosts the New England Revolution on Saturday.
