Stefan Frei is back in the Seattle Sounders' starting lineup after missing last week's game with an arm injury. Frei had been training with the first team most of the week. Joining him are Nelson Haedo Valdez and Jordan Morris, both of whom left the Real Salt Lake match with injuries.
Morris appeared to have sustained some kind of head injury but was quickly cleared of a concussion. Valdez appeared to injure his thigh, but also trained most of the week.
With those three, the Sounders are able to use what is pretty close to a first-choice group. The only exceptions are Zach Scott in for the injured Brad Evans (shoulder) and Cristian Roldan for Erik Friberg (MCL).
Sounders lineup: Frei; Mears, Scott (C), Marshall, Jones; Alonso, Roldan, Ivanschitz; Morris, Valdez, Dempsey. Bench: Remick, Miller, Fisher, Alfaro, Sturgis, Kovar, Anderson.
Whitecaps lineup: Ousted; Aird, Waston, Parker, Harvey; Laba, Morales; Bolaños, Pérez, Manneh; Rivero
