Mark Murphy confirms the signing:
The Celtics, their needs still unaddressed at backup point guard, made a strong move today to add defense and strength to their frontcourt with the signing of veteran power forward P.J. Brown.
The 36-year-old Brown played for Chicago last season before going into semi-retirement. He was also pursued by the Celtics last summer, but expressed a preference to remain near his home in Louisiana, though he ultimately didn’t sign with two of his supposed targets - New Orleans and Dallas.
He is consided a rugged defender and rebounder - especially at the `four’ spot - and should provide the Celtics with yet another accomplished role player.
UPDATE: The Celtics have officially announced the signing . -R.H.
