Seattle Seahawks quarterback Russell Wilson does not intend to sign a contract extension with the team this season if he does not reach an agreement by his self-imposed deadline of midnight Monday, sources told ESPN's Adam Schefter.

It will be a challenge to get a new deal done by that deadline, though the sides are trying as talks continue, sources told Schefter.

Wilson's contract is up after this season. If a new contract is not agreed on, the Seahawks presumably will place their franchise tag on Wilson.

Wilson is expected to participate in all of the Seahawks' offseason activities and attend training camp.

As for suggestions that the Seahawks could trade Wilson if he does not sign a new deal, there are no obvious teams willing to surrender draft picks or pay Wilson what he is seeking, sources said.
