Oklahoma City Thunder GM Sam Presti confirmed that contract negotiations between the team and representatives for Jeff Green have ended.

Green will become a restricted free agent during the summer of 2011.

"Signing a player to an extension is certainly a positive but has become more unique," Presti said. "We explored the concept and had positive dialogue, but we will have to revisit the discussions in the future."

Kevin Durant signed a maximum contract extension in July.

"I totally understand it," Green said Thursday. "There are a whole lot of reasons it couldn't get done right now, but I'm not worried about it. I'm just thinking about this season and what I've got to do."
