Outlook: Kickers, who play in top minor league division, eliminated United at this stage last year, 2-1, in Richmond. . . . All-time series between teams is even, 2-2-1. . . . Richmond is 10-6-5 in league play and in second place behind Montreal, but has gone four games without scoring (a 1-0 loss and three 0-0 ties). . . . Matthew Delicate (Virginia Commonwealth) leads team with eight goals. Midfield is guided by former United standout Richie Williams. . . . Kickers advanced with 8-4 victory over amateur team from New Jersey last month. . . . United, which received bye to this round, hasn't played since 2-1 loss to defending English champion Chelsea last Thursday at FedEx Field. . . . D.C. won this tournament in 1996 and finished second the following year. . . . If United (8-6-5 in MLS) wins tonight, it will host Dallas or Columbus in Aug. 24 quarterfinal at Maryland SoccerPlex in Germantown.
