Celtics president Danny Ainge continues revamping the roster with two more transactions in the offing.

The Celts reportedly are close to acquiring point guard Nate Robinson from the Nuggets for point guard Jameer Nelson. Robinson, who played for Boston in 2010 and 2011, isn’t expected to spend much time on the court, however, as he will apparently get a buyout from the Celtics, with the Clippers a potential final destination. Robinson is averaging 5.8 points, 1.2 rebounds and 2.3 assists this season.

The Celtics also are reportedly close to executing a buyout of forward Tayshaun Prince, who was acquired Monday in a trade that sent Jeff Green to the Grizzlies. A source close to the situation, however, told Sporting News’ Sean Deveney on Tuesday that no substantive buyout talks have taken place.

Prince averaged 7.3 points and made 45.5 percent of his 3-point field-goal tries in 24.2 minutes per game for the Grizzlies this season. The Clippers, Mavericks and Thunder are rumored to be interested in Prince. 

With the two moves, the Celtics will soon have two open roster spots. Could another trade be coming? Mad scientist Ainge isn’t messing around; he already has traded Rajon Rondo, Austin Rivers, Brandan Wright and Green to prod

uce massive amounts of cap space and a plethora of draft picks in 2015 and 2016.
