The Sounders will be without the services of backup goalkeeper Terry Boss when the team takes on Toronto FC Saturday.
Boss was called up to the Puerto Rican national team to play two matches during the Caribbean Championship. On Saturday, Puerto Rico will play Anguilla and then will play Saint-Martin on Monday.
Boss, who gained eligibility for the team after playing with the Puerto Rico Islanders of the USL, has already earned four caps. Sounders teammate Taylor Graham has also played four matches with Puerto Rico, even scoring a goal.
