WASHINGTON (AP) - D.C. United rookie midfielder Brandon Barklage is done for the season after having reconstructive knee surgery.
Barklage is being put on the season-ending injury list, allowing for a roster replacement.
He injured his anterior cruciate ligament during United's 2-1 victory over Harrisburg in the U.S. Open Cup quarterfinals last week.
Barklage's rehabilitation is expected to take about six months.
"Brandon was enjoying a great start to his career and we expect great things from him in the future," United general manager Dave Kasper said Friday.
"His injury was an unfortunate event, but we look forward to a full recovery and seeing Brandon ready for preseason next year."
