What happened: Seattle Sounders Fc said the deal applies after any club victory and must be redeemed in the McDonald's app. Fans need to make a $2 purchase to unlock the free sandwich.

Why it matters: The perk gives Seattle another post-win fan incentive during the MLS regular-season run-in. It also keeps alive the same post-win McChicken promotion the club has been pushing since late September.

What to watch: The next Seattle win would activate the offer again under the current terms.
