The Seattle Sounders will be without star defender Chad Marshall for the second leg of the MLS Western Conference semifinals against the Portland Timbers on Thursday night. The center back needed surgery to repair cartilage in his right knee, head coach Brian Schmetzer reported at training Tuesday.

Marshall suffered the injury during the first half of the Timbers' 2-1 victory in the first leg on Sunday. Also hurt was midfielder Cristian Roldan, who is day-to-day with a hip flexor strain. Schmetzer said Roldan will be a game-time decision.

"We'll see if he can make it," Schmetzer said. "He's a pretty strong, mentally, kid."

A finalist for MLS defender of the year, Marshall has started in all but four of the Sounders' regular-season and playoff matches in 2018, and has a total of 401 MLS regular-season appearances. The Sounders did not indicate whether he could return if they continue to advance.

Panamanian international Roman Torres, who replaced Marshall in the 40th minute Sunday, is expected to start Thursday and be paired defensively with Kim Kee-hee. The two have started together in only two matches -- at San Jose on July 25 (a 1-0 win) and at the LA Galaxy on Sept. 23 (a 3-0 loss).

"Certainly, that pairing hasn't played a lot together, so we'll do what we can to get them in sync. But they are two very talented players," Schmetzer said. "Roman was waiting for his chance and here it is. He'll be ready."
