After losing by four goals its last time out, Chivas USA will try to bounce back in a place where it last fell by that margin.
No team has played fewer games than Chivas USA (7-9-5), which sits in seventh place in the Western Conference with 26 points - 11 out of a playoff spot.
"You've got games in hand," coach Robin Fraser told Chivas' official website. "That doesn't mean anything unless you win those games. Games in hand gives you a lifeline that you either take advantage of or you don't."
Chivas missed a chance to gain ground with Sunday's 4-0 loss to archrival Los Angeles, which finished with a 12-3 advantage in shots on goal.
"We did a lot of things to hurt ourselves against the Galaxy," Fraser said. "We gave up spaces that we shouldn't have and, as a result, we find ourselves chasing the game."
It marked Chivas' worst defeat since it fell by the same score April 28 at Colorado, dropping to 0-5-1 in the last six meetings.
Chivas has been outscored 13-2 in going 0-3-1 in its last four trips to Dick's Sporting Goods Park. Casey has totaled four goals in those matchups and has returned to training this week after being out with right hamstring tightness.
"The leg's going good, just trying to work on my fitness and get sharp and get available for the weekend," Casey told the league's official website. "I'm hoping to be available."
The Rapids (8-15-1) could use Casey after they were left lamenting numerous missed opportunities in last Saturday's 3-2 loss at FC Dallas.
"That's what the game is," coach Oscar Pareja told the Rapids' official website. "You've got to put the ball in the back of the net, and if you don't do it, then you pay for it."
The Rapids continue to get little out of Omar Cummings, who has no goals or assists over his last five games. The forward has come up empty on his last 12 shots.
Cummings has a history of producing against Chivas with five goals and five assists in nine matchups.
Kamani Hill scored twice for the Rapids in the first matchup, but he's gone a season-high 10 straight games without a goal.
Chivas is looking for improvement in its second game with Shalrie Joseph, acquired Aug. 3 from New England. Joseph was part of a midfield group that was thoroughly outplayed Sunday.
"The more practice and the more games I get, the more comfortable I will get with my teammates," Joseph said.
Chivas has played better all year on the road, going 4-2-3.
"It's an opportunity to go out and show who we are and how we bounce back from that," Fraser said.
