Brown's deal is now official, and the reported terms of the extension are $115 million over four years. The entire contract isn't guaranteed, however. The Athletic's Jay King reported there are $12 million in incentives as part of the contract.
Later on, Yahoo Sports' Chris Haynes reported the specifics of Brown's incentives:
Yahoo Sources: On Jaylen Brown's four-year extension, he can secure $8M in incentives if he wins MVP, DPOY or makes one of three All-NBA Teams. He pockets $4M if plays 65 or more games, team wins 49 or more games and reaches second round of playoffs. Total guaranteed salary $103M

Haynes also reported Monday that Brown's new contract "does not contain a team option or player option."
The 22-year-old forward would have been a restricted free agent next summer if he and the C's didn't come to an agreement before Monday's deadline. It's the first rookie extension for a Celtics player since 2009 when Rajon Rondo inked a five-year contract.
Brown has averaged 11.2 points and four rebounds per game on 46.2 percent shooting and 36.5 percent from 3-point range over his first three seasons. He's also a very versatile defender with his 6-foot-7 frame and impressive strength.
