Brook Lopez is an unrestricted free agent.
In a move that was expected, the 7-footer officially has opted out of the final season of his contract, according to a NBA source.
Lopez was due to collect $16.7 million in the last season of the four-year, $60-million pact he signed with the Nets in 2012.
He bounced back this past season after a couple of injury-filled years, averaging 17.2 points, 7.4 rebounds and 1.8 blocks.
Lopez's decision came four days after Thaddeus Young exercised his opt-out and less than 24 hours after the Nets traded center Mason Plumlee to Portland during Thursday night's draft in exchange for small forward Rondae Hollis-Jefferson, who was drafted by the Trail Blazers out of Arizona, and veteran point guard Steve Blake.
Though nothing is guaranteed in free agency, the perception is that the Nets will re-sign both players. The team officially can begin negotiating new contracts with them when free agency begins Wednesday.
