Derek Carr tweeted Thursday that he has finalized a five-year extension with the Oakland Raiders that sources indicate is worth $125 million.

Carr's new deal, which carries an average salary of $25 million, will make him the NFL's highest-paid player in terms of new money average.

He suffered a broken fibula in Week 16 and missed Oakland's playoff loss to the Houston Texans, but he has been a full participant in the team's offseason activities.
