James Posey will be playing in Boston next season alongside Ray Allen, Kevin Garnett and Paul Pierce.
“He was a free agent,” team spokesman Jeff Twiss said Sunday. “He was available to be signed and he decided to sign with us.”
Posey will make between $7 and $7.5 million over the course of the deal, although the second season is a player option. The Celtics used most of the remainder of their mid-level exception to sign Posey, who spent the past two seasons with the Miami Heat.
