The Seahawks have awarded a multiyear contract extension to head coach Pete Carroll, all but ensuring he will coach nowhere else and finish his decorated career in Seattle, league sources told ESPN.

The deal is believed to make Carroll among the highest-paid coaches in the NFL, sources told ESPN.

The Seahawks made the move quietly, long before their game Sunday in Buffalo against the Bills, according to league sources.

Although no one in the Seahawks organization has confirmed the extension, one source told ESPN that the belief is the deal will tie Carroll to Seattle through the 2025 season, when he will be 74 years old.

Carroll, who turned 69 in September, is the NFL's oldest head coach, but few can match his energy and positivity. The Seahawks are right in the thick of the NFC West title hunt again this season, entering Sunday with a 6-1 record, and quarterback Russell Wilson playing at an MVP level.

Now in his 11th season with the Seahawks, Carroll is the winningest head coach in franchise history with a record of 106-60-1. Carroll has led Seattle to eight playoff appearances, four NFC West titles, two Super Bowl appearances and one Super Bowl victory.
