Kevin Garnett has agreed to waive his no-trade clause, clinching an agreement on a trade that will land Paul Pierce, Garnett and Jason Terry with the Brooklyn Nets. Garnett waiving the no-trade clause was the last step to sealing the deal, sources said.

Brooklyn has agreed to send three first-round picks (2014, ‘16 and ‘18) along with Kris Humphries’ expiring contract, Gerald Wallace, Kris Joseph, MarShon Brooks and a sign-and-traded Keith Bogans to the Celtics for Pierce, Garnett and Terrys.
