Portland Timbers coach Caleb Porter did not know as of Wednesday whether five key players would be available for Saturday's game at Real Salt Lake.

Porter said the club was still evaluating captain Liam Ridgewell (quad injury), forward Fanendo Adi (hamstring injury), left back Vytas (shoulder injury), forward Darren Mattocks (knee contusion) and goalkeeper Jeff Attinella (sore shoulder) ahead of Saturday's game.

"I don't have a ton of information on all these guys because we just had one training so far this week with recovery coming back from New York," Porter said. "I don't have a lot of clear answers on a lot of these questions with regards to whether or not they are going to factor into the game... I'll know more tomorrow or Friday."

While Ridgewell, who has made just one appearance in the last 14 games, has been back in training, Porter said the club was still evaluating whether the 33-year-old center back would be 90 minutes fit in time for Saturday's match.

Porter said Adi was starting to work his way back into training after missing the last five games with a hamstring injury, but he also said it was too early to tell whether Adi could be available for Saturday's game.

Vytas and Mattocks both left last Saturday's match against New York City FC with injuries and Porter did not yet know the severity of either injury.

Attinella hurt his shoulder making a save during the match at NYCFC, but was able to stay in the game. Porter did not speculate on Attinella's availability for Real Salt Lake, but the fact that he was able to finish the match at NYCFC is a good sign.

Porter said that goalkeeper Jake Gleeson, who had been dealing with a hamstring injury, was healthy and has been back in training since last week. Porter did not say whether he plans to start Gleeson or Attinella moving forward. Gleeson entered the season as the No. 1 goalkeeper, but Attinella has played well in Gleeson's absence over the last four weeks.

Timbers defender Marco Farfan remains out and could be sidelined for another few weeks after reinjuring his ankle while competing for T2.

The Timbers will also be without midfielder Diego Chara Saturday at Real Salt Lake. Chara will serve a suspension for yellow card accumulation during the match.
