New England is also having a hard time registering goals, and it would love to finally break out of that slump Saturday as it tries to avenge last month's blowout loss to the Dynamo.
These teams began the 2014 season March 8 in Houston, where Dynamo forward Will Bruin scored twice in the first 13 minutes and assisted on Boniek Garcia's goal 10 minutes later en route to a 4-0 rout.
Houston followed with a 1-0 win over Montreal the following week, but it has been outscored 6-2 in back-to-back defeats. It was deadlocked at 1-all with FC Dallas last Saturday before defender David Horst was given a red card in the 60th minute, and Dallas scored three times in the next 10 minutes to come away with a 4-1 win. Horst is suspended for this match.
"We should've done better. Those 10 minutes were not good enough," goalkeeper Tally Hall told the Dynamo's official website. "Definitely frustrating, even though I'm optimistic about what we have and the talent we have on the team and the way we're able to play.
"We move on from what was a disaster ... and know we have one game this weekend that we've got to win."
The Revolution have yet to move on from their disastrous performance in the opener. They've been shut out in three of four games since and are last in the league with two goals, which came in their only win March 29 at San Jose. One of those was an own goal on the Earthquakes.
Midfielder Lee Nguyen has scored the only goal for New England (1-3-1), which fell 2-0 on the road last Saturday to a D.C. team that entered on a 15-match winless streak.
"For us, we just take it game by game," forward Charlie Davies said. "We were trying to go out there and get three points, which is unfortunate. But I mean it is a long season, there is going to be ups and downs. It is better to lose now than late in the season."
The Dynamo are 2-2-5 in nine visits to New England, including a win and three draws in the last four.
"I don't think guys forget the fact that we went (to Houston) and we lost 4-0," Revolution goalkeeper Bobby Shuttleworth told the team's official website. "We've got to make (Gillette Stadium) a fortress. We want them to come in here and we want to let them know that we're going to be ready to play."
Captain Brad Davis assisted on Ricardo Clark's goal in the 41st minute that tied the match last week for Houston (2-2-0), but he was forced to leave with an ankle injury. Davis leads the team with two assists.
"He's a bit day to day," coach Dominic Kinnear said. "We're trying to get him ready for the weekend, so we'll see how it goes."
Bruin, one off the league lead with three goals, has scored four times in six games against the Revolution.
New England will be without coach Jay Heaps after he was dismissed late in last week's match, resulting in a one-game suspension. Former D.C. coach Tom Soehn will take over.
