The Seattle Seahawks are being put up for sale

• Allen's instructions were "to eventually sell his sports holdings and direct all Estate proceeds to philanthropy," the team said.

What they're saying: "This is the first time a team that won the Super Bowl has been put up for sale in the same year," writes Bob Condotta of The Seattle Times.

Flashback: Allen, Microsoft's co-founder, agreed to buy the Seahawks in 1997 and was a controlling owner until his death in 2018, The Athletic reported.

Yes, but: NFL rules state that a team's controlling owner must be an individual, per The Seattle Times — not an entity like the Paul G. Allen Trust.

What's next: The sale process is expected to continue through the 2026 offseason, per the team's announcement.

• NFL owners must ratify a final purchase agreement, the team said.
