Coach Sigi Schmid said Ljungberg was just given a break due to general soreness. Schmid also implied that he was also just being cautious with Riley, who tweaked his right ankle in training on Tuesday.
However, Riley himself seemed uncertain if he will be able to go Saturday when the Sounders kick off at Kansas City.
"The training staff and I attacked it early," Riley said. "The first 48 hours are always the most important, and I thought we did fantastic in doing that. I got a light workout today, we’ll see how it does tomorrow. ... I try to stay positive and optimistic, for sure. Obviously it’s a big game. I definitely want to contribute in any if, if (only) from the bench and cheering guys on, or if it’s on the field I’ll do what I can to get us into the playoffs."
