Per ESPN, the Seahawks will receive defensive lineman Shelby Harris, quarterback Drew Lock, tight end Noah Fant, two first-round picks, two second-round selections and a fifth-round pick. The Broncos will also receive a fourth-round selection.
Wilson has waived his no-trade clause and agreed to a new contract in principle, ESPN reported. The deal has been in the works since Saturday, per the network.
The deal cannot be finalized until the new league year begins on March 16.
NFL Network reported the Seahawks had multiple offers in play for Wilson, however the Broncos upped their bid to edge Washington, among others teams.
