The Sounders host San Francisco of Panama tonight in the resolving match of this CONCACAF Champions League preliminary round match.
The Monks hold a 1-0 lead in the aggregate-score two-game series, so a win or a tie eliminates the Sounders. If the total score is even at the end of regulation, the first tie-break is road goals. If still even, it goes to 30 minutes of added time. If still even, PKs.
The winner goes on to group play, which will be made up of home-and-away games with three other opponents in the group.
