The New York Jets have locked up linebacker Quincy Williams with a three-year, $18 million contract, according to a source.

The deal can be worth as much as $21 million and it includes $9 million in guarantees.

The Jets had identified Williams as one of their top priorities.

Williams, the older brother of Jets star defensive tackle Quinnen Williams, made $2.54 million last season in the final year of his rookie contract.
