"The Thunder has traded Jeff Green and Nenad Krstic to the Boston Celtics for center Kendrick Perkins, according to multiple reports.

Perkins could supply the interior defense the Thunder has lacked.

Perkins, Green and Krstic all are in the final years of their contracts, so the trade could prove to be for 2011 playoff purposes only.

Some reports say Celtic backup point guard Nate Robinson is also part of the deal."
