In two seasons since leaving Oregon, the 6-foot-7 Jackson has averaged 2.7 points and 7.8 minutes in 46 games. He missed 32 games last season with a broken left wrist.
Jones averaged 1 point and 2.2 rebounds in 6.2 minutes in 14 games for Boston as a rookie last season. He signed with Minnesota as an undrafted free agent out of Saint Joseph's and was traded in a deal that also brought forward Wally Szczerbiak to the Celtics.
Boston also received an undisclosed amount of cash as part of the deal for Jackson.
