The Portland Timbers will once again be dealing with major absences Wednesday night when they host the Colorado Rapids.

Timbers captain Liam Ridgewell (quad injury) and goalkeeper Jake Gleeson (hamstring injury) remain out and will not be available for either Wednesday's game against Colorado or Sunday's rivalry match against the Seattle Sounders. Timbers forward Fanendo Adi (hamstring) remains questionable for both matches.

"We don't know if any of them will be available for this week," Timbers coach Caleb Porter said.

Ridgewell, who has missed 10 of the last 11 games with a quad injury, has not been healthy enough to participate in training. Porter said he is hopeful that Ridgewell will return to practice by the end of the week or early next week.

"The good news is we have two weeks off after this window here," Porter said. "We're looking to be in good shape with a lot of these guys (when we get back from the break)."

Porter said Adi was in the final stages of his return to play protocol and the club was still evaluating his status for Wednesday and Saturday. As a forward, Adi plays a position where he can be used off the bench for limited minutes, making it more feasible that he could see playing time this week even if he is not yet healthy and fit enough to play 90 minutes.

"For Wednesday, we're not sure (on his status). For Sunday in Seattle, we're not sure, but Adi is looking like he's getting very close," Porter said.

Porter said that Gleeson is progressing as well, but would not be ready in time for either game this week.

Timbers left back Marco Farfan, who has been dealing with a sprained ankle, returned to training Monday.

Porter said Farfan wouldn't be available Wednesday as he continues to build up fitness. Porter said Farfan could potentially factor into Sunday's rivalry game at Seattle, but that the club might also opt to give him a game with T2 this week to help him work his way back up to full fitness.
