Midfielders Andre Lewis and Marco Bustos will miss the fixture for Vancouver while defender Diego Rodriguez is probable after recovering from a quad strain. DC United are without the quartet of midfielders Markus Halsti and Collin Martin, defender Steve Birnbaum, and forward Eddie Johnson ahead of the match.
A clash of early season titans as Vancouver, despite having a game in pocket over the Western Conference, are in the top spot as the best team in the MLS on 16 points so far. DC United have a game in pocket over New York Red Bulls, who occupy the top spot in the East, but are tied with the Revs on 11 points.
Vancouver have 4 wins and only 1 loss in their last 6 games in the league. The Whitecaps have also won 2 and drawn 2 against DC since United won the first ever meeting between the two sides.
DC are on a 4 game unbeaten run and have won 3 and lost only 1 game in their last 6 in the MLS. The last 2 meetings between the two at BC Place have ended 0-0, meaning the two clubs have not scored a goal in Vancouver since 2011.
Prediction: Possibly more of the same. The offensive power means there might be a long feeling out period in the first half. Should be a lively second though.
