FIFA will contractually have the right to basically do whatever they want with all the cities. They have “full control of what goes on inside and outside the building from 30 days before the first match to seven days after the last”
So definitely no way are they sharing the street with MLB in Seattle for a baseball game on the same day as a football game. Not even if they suggested a 10am start for the Mariners to get it done and out of the way.
The schedule release must have been delayed while FIFA threw their weight around with all the cities hosting games. Absolute bastards they are, but it would be contractually their right to do so,
FIFA contract wrote:FIFA also has the “non-exclusive right to have free and unrestricted access to visit and inspect the stadium” at no cost, at any time.
The stadium shall be provided to FIFA free and clear of any advertising, merchandising and brand recognition and it will not be known as Lumen Field when the tournament kicks off. FIFA has the power to temporarily rename the stadium, to remove any reference to the naming rights sponsor, owner or user of the stadium.
It would not surprise me that FIFA would even object to the T Mobile sign on the baseball stadium as it would be visible on the drone or blimp shots of Lumen. It’s not unreasonable under that contract to have the T Mobile sign obscured from mid May to mid July. Some would say it’s an improvement, well played FIFA.

They are such a controlling governing body that the hatred towards them worldwide far outweighs any feeling the US has towards NFL, MLB and NBA combined.
I guess that the other host cities don’t have a baseball park so close to the soccer stadium, but I don’t know all those cities well enough to say. So the schedules of the other host cities hence the Dodgers, Giants, Red Sox, Yankees etc will not be as affected as the Mariners.
If someone ran their eyes over all schedules I wouldn’t mind betting a few pounds that we are the only team with a scheduled double header in 2026.
