Seattle Sounders coach Sigi Schmid will continue to look at trialists this week.
After cutting loose five USL Seattle Sounders players on Friday, Schmid has added another four hopefuls to his preseason squad.
Third-round draft pick Jared Karkas, former Kansas City Wizards forward Ryan Pore, former D.C. United forward Quavas Kirk and first-year forward Jeff Clark, who played at Concordia College in California.
"We're moving forward," Schmid told the Seattle Times. "Some guys have done well and they're going to continue to be with us, and some guys, we're going to move forward on and look at other players."
