TUKWILA — The Sounders have been dealt a pair of serious injuries to two depth players.

Seattle announced Tuesday that forward Kevin Parsemain, who was on the bench in Saturday’s 4-4 tie against Portland, has suffered a torn anterior cruciate ligament (ACL) in his knee and will require surgery, likely ending his season.

Also, rookie defender Damion Lowe, the team’s first-round draft pick, underwent hip surgery Monday and is expected to be out four months.

The Sounders have the option to recall any of three players out on loan with other teams — forward/midfielder David Estrada, and defenders Eriq Zavaleta and Jimmy Ockford — but coach Sigi Schmid indicated that won’t likely happen.

“Right now, in the short term, it probably doesn’t change anything,” Schmid said of the injuries’ effect on the roster. “It might change some things long term.”

If Parsemain and Lowe are placed on the disabled list, two spots could open up for midseason signings.

Parsemain suffered his injury in Sunday’s reserve game, a 3-1 win against Oregon State. The 26-year-old from the small Caribbean nation of Martinique had signed two weeks ago following a standout preseason.

Schmid said a surgery date will be set once the swelling goes down in Parsemain’s knee and he regains more range of motion.

Lowe had complained of hip discomfort a couple of weeks ago, and when rest didn’t improve his condition, the team used an MRI and discovered a tear. Surgery was deemed necessary after consultation with specialist Marc Philippon in Colorado.

The Sounders already are dealing with a pair of injuries as midfielder Andy Rose has missed two games with hamstring tightness and team captain Brad Evans has missed three games with a calf issue.

“Evans, we’re being really slow with because he has a tendency to push too hard too quick, and we think that’s why he’s set himself back a little bit,” Schmid said. “So we want to make sure that if he’s not ready for Dallas this weekend that he’s definitely going to be ready for Chivas the next weekend.”

Dempsey finally in rhythm

Off to a scintillating start, Clint Dempsey admitted Tuesday that he feels as comfortable as ever with the Sounders, eight months removed from his attention-grabbing return to MLS. The U.S. international has four goals in just 213 minutes this season, tied for the league lead, after scoring just once in 921 minutes in 2013.

So what has been the difference?

“I think it was difficult for me (last year) trying to jump into a league where everybody was already past midseason form, and adjusting to playing games and the travel and the turf — the toll that it takes on you,” Dempsey said.

“But now I feel good. I feel like I’m in a rhythm.”
