The Oklahoma City Thunder are now without two starters for the duration of the 2013-14 regular season as shooting guard Thabo Sefolosha has been ruled out for 4-6 weeks due to a left calf strain. The Thunder also don't have center Kendrick Perkins available for at least six weeks after needing surgery to help his strained groin.
