Portland Timbers captain Liam Ridgewell will miss Saturday's game against the Houston Dynamo while defensive midfielder David Guzman and left back Vytas remain questionable for the match.

Ridgewell is dealing with a foot sprain and is expected to miss at least the next two weeks. Timbers coach Caleb Porter said that Ridgewell will most likely return to the field when Portland hosts the New England Revolution on April 2.

"We're looking for him probably for the New England game most likely, but we will see," Porter said. "Things can change. Maybe Columbus, but most likely New England."

Guzman separated his shoulder during Sunday's match at Los Angeles and will miss at least the first few days of training this week. Porter said that the Timbers will evaluate Guzman later in the week to determine whether he could be available Saturday when the club hosts the Dynamo.

"With that injury it's day-to-day because these guys aren't baseball players where they use that shoulder a ton," Porter said. "It has to be calmed down enough where it's functional. He will definitely miss a couple days of training and may be questionable for this match."

Vytas, who is dealing with a calf strain, is also "day-to-day." Porter said the club would have to evaluate Vytas later in the week to see if he would be healthy enough to play Saturday.

"He could be available, but it might be tight for this game," Porter said.

Roy Miller is expected to once again replace Ridgewell in the lineup Saturday, while Marco Farfan would once again be the likely replacement at left back if Vytas can't go.

Porter said that the Timbers have a couple of options at defensive midfield if Guzman can't play Saturday. The Timbers could either turn to Ben Zemanski to replace Guzman or move Darlington Nagbe to the No. 8 position and start either Darren Mattocks or Dairon Asprilla on the wing.
