WASHINGTON (AP) - D.C. United midfielder Chris Pontius has had another surgery on his left hamstring.
United said Wednesday that Pontius is expected to miss four to six months.
Injuries have frequently interrupted a promising career that began when Pontius was a MLS Rookie of the Year finalist in 2009. He had injury-shortened seasons in 2010 and 2011. In November, he had surgery to repair his left hamstring and sciatic nerve.

Pontius had hoped to recover in time for the start of this season, but he had a setback that led to his latest surgery.
Pontius has 27 career goals in six MLS seasons, including a career-high 12 in 2012.
