When Brad Evans went up for a virtually uncontested header in the 87th minute, it looked like a relatively innocuous play. But when Dom Dwyer backed into Evans, it sent the center back tumbling. Evans' shoulder bore the brunt of the impact with the FieldTurf, and he immediately screamed in agony.

Physicians rushed onto the field and Evans was ultimately removed from the match. He was sporting a sling in the postgame locker room.

Sounders head coach Sigi Schmid indicated that Evans had dislocated his shoulder

"It popped out, it popped back in," Schmid said. "It's not about healing, it's about the pain. He could play within a week."

Assuming Evans can't return for Saturday's game against Real Salt Lake, that almost certainly means Zach Scott will get his first start of the season. The more interesting scenario is what happens at right back, where Oniel Fisher won't be available due to his red card and Tyrone Mears may or may not be healed from the quadricep strain that kept him out of this one.

No one else on the roster has much experience at right back, but Cristian Roldan played there for much of the second half.
