Marc Stein of ESPN reports:

Highly coveted free agent Troy Murphy is signing with the Boston Celtics.

Murphy told ESPN.com via e-mail that he will join the Celtics after spending much of the past 48 hours agonizing between Boston and the Miami Heat. Murphy reached terms of a buyout with the Golden State Warriors on Sunday.

Murphy also received recruiting pitches this week from Portland, New York and Orlando, sources said, but the 6-foot-10 forward was always determined to sign with a top contender in anticipation of making the first deep playoff run of his career. Murphy has played in more games (639) than any other active player without appearing in the playoffs.
