Hurtado's MRI revealed an MCL sprain that will keep him out this week, but perhaps not much beyond that.
Meanwhile, O'Brian White has come off the injured list and could return to action Saturday against Colorado or next week in the Manchester United friendly. In either case, he says he's fully over the blood clot issue, and all that remains in getting into game shape.
Here's the Sounders announcement about White coming off the injured list:
Seattle Sounders FC forward O'Brian White has been removed from the club's Disabled List, making him immediately eligible to participate in MLS games.
White, 25, was placed on the Disabled List on April 27 and underwent surgery to remove a blood clot. He has not appeared in any competitive matches since April 22.
White, who was acquired by Sounders FC in an offseason trade with the Vancouver Whitecaps FC, has started all seven appearances in 2011 and scored two goals and two assists.
The Sounders FC hosts the L.A. Galaxy in a Lamar Hunt U.S. Open Cup quarterfinal match at Starfire Sports Stadium on Wednesday at 7 p.m. PT and then plays the Colorado Rapids on Saturday at 1 p.m. PT on the Xbox Pitch at CenturyLink Field.
