Randolph was traded to Boston on Thursday in a three-team deal that sent Austin Rivers to the Clippers and Reggie Bullock to the Suns, ESPN's Marc Stein reports. Randolph, who's appeared in only 16 games for the Suns, is essentially a throw-in in the deal and could be waived by the Celtics in short order. The former Duke standout has played for five NBA teams since entering the league in 2005 and spent a brief, 16-game stint in Boston during the 2012-13 campaign.
