D.C. United midfielder Ian Harkes, who has started all but three matches in his rookie season, will miss three to four weeks with an ankle injury, Coach Ben Olsen said Tuesday.
Harkes, a homegrown signing from Gonzaga High School and Wake Forest University, was injured early in the 4-0 defeat at Minnesota on Saturday and did not return for the second half. He has posted two goals and an assist in the past seven matches.
Meantime, midfielder Rob Vincent is out indefinitely with recurring knee problems. He hasn’t played since the opening month of the season and, after undergoing routine knee surgery in late March, developed a blood clot that sidelined him several months.
