Tom Brady has finalized his long-term contract extension, Peter King reported at halftime of NBC's coverage of the Vikings-Saints season-opening game.

King's source was none other than Patriots owner Robert Kraft, who declined to divulge the terms of the extension, except to say that it was a four-year deal, which would keep Brady in New England through 2014. Brady had been entering the final year of his contract.

Brady is expected to sign the new deal Friday.

The news came on the same day that Brady was involved in a two-car accident. Brady wasn't hurt in the early-morning accident, but a passenger in the other vehicle had to be taken to a hospital for treatment.

Fellow elite QBs Peyton Manning and Drew Brees also are beginning the final year of their contracts, with the threat of a lockout by owners on the horizon.
