The Thunder freed up a roster spot in their trade with the Timberwolves on Monday, which will allow them to make another move this summer.

Oklahoma City has just 12 players under contract after acquiring Etan Thomas and two second-round picks from Minnesota for Damien Wilkins and Chucky Atkins.

The Thunder could fill the roster spot by re-signing Desmond Mason or adding a third point guard to play behind Russell Westbrook and Shaun Livingston.
