FC Dallas' offense has been in a groove lately, even without Fabian Castillo.
The club figures to be even more potent Sunday night when Castillo returns from suspension at Chivas USA.
Dallas (8-7-6) has scored two or more goals five times during its 3-0-3 stretch and comes off a 2-all draw at Vancouver last Sunday. It marked the final match of Castillo's four-game suspension, who was disciplined after making physical contact with an official following the team's 2-2 draw in Portland on June 11.
Castillo, the club's third-leading scorer with five goals in league play, had a goal in each of his last two matches. He also scored in a 3-1 home win over Chivas on March 22, and netted the equalizer in the 83rd minute of a 1-all draw on May 17.
Dallas is 6-1-5 in the last 12 meetings between the teams, including 3-0-4 in the last seven at home.
New captain Matt Hedges is expected to be available after leaving Sunday's match at halftime due to concussion-like symptoms. Hedges was given the armband after Dallas traded Andrew Jacobson to New York City FC Tuesday for a third-round pick in the 2016 SuperDraft.
Hedges has played in a team-high 20 matches this season and has made 81 league appearances for Dallas since beginning his career in 2012.
"It means a lot to me," Hedges told the team's official website. "It took a lot of faith for Oscar to put me in this position and I'm excited and ready to lead the team for the rest of the year."
Chivas (6-9-5), meanwhile, is tied for the league's fewest goals with 21. Its defense has also fallen off lately, surrendering three goals in two straight losses after conceding one during a club record-matching four-game winning streak.
Coach Wilmer Cabrera made five changes to his starting 11 following a 3-1 loss at D.C. United on July 20, but the team was outshot 16-4 in a 3-0 defeat in Colorado on July 25.
"You can make excuses about altitude, travel and things like that all you want, but we didn't play well enough," forward Eriq Zavaleta told the league's official website. "We made mistakes that we've made continually throughout the year. They are things we need to fix if we want to make a playoff push."
Chivas' Erick Torres - the lone All-Star on either roster - saw his scoring streak come to an end at six consecutive matches, though he's still tied with Kansas City's Dom Dwyer for second in the league with 14 goals.
