Maybe Arjen Robben could drop by RFK tonight. D.C. United needs a goal scorer — stat!

United, which has gone nine straight without a win, welcomes the Portland Timbers, who have gone 10 straight without a loss.

My print/online story introduces Canadian midfielder Kyle Porter, who scored his first career MLS goal last weekend.

Dejan Jakovic (groin strain) was undergoing a fitness test a few hours before kickoff but doesn’t seem likely to play.

The Capital Weather Gang has the game-time forecast.

Kickoff: 7 p.m. ET.

TV: Comcast SportsNet, Univision Deportes.

Referee: Jose Carlos Rivero.

Homegrown forward Michael Seaton, 17, scored his second goal of the season while on loan with the third-division Richmond Kickers, a 66th-minute finish Friday night to cap a 2-0 victory over the Harrisburg City Islanders. Richmond (5-0-3) will host United on Tuesday night in the third round of the U.S. Open Cup. Skip ahead to the 2:50 mark to see Seaton’s goal:
