The Oklahoma City Thunder are unlikely to agree upon an extension with Reggie Jackson, which will allow him to become a restricted free agent in 2015.

The Thunder will have the right to match any offer Jackson receives from another club.

Oklahoma City agreed upon extensions with Kevin Durant, Russell Westbrook, Serge Ibaka and Thabo Sefolosha, but were unable to with Jeff Green and James Harden. Green was traded at that season's deadline, while Harden was dealt before the extension deadline.
