The Oklahoma City Thunder need their full complement of players in order to give themselves the best chance at winning this second round series against the Los Angeles Clippers. They're unlikely to have that to close out Game 6 thanks to a calf injury suffered by Thunder big man Serge Ibaka. 

Ibaka limped off the court with 7:24 left in the third quarter and the Thunder trailing the Clippers 59-54. Ibaka had just knocked down a jumper a minute earlier, but left the court and went to the locker room. He has a calf injury and is doubtful to return in Game 6.

If the Thunder don't win Game 6 and have to go back to a Game 7 in Oklahoma City, they'll need Ibaka and his defense against Blake Griffin and the rest of the Clippers. We'll monitor and update with any further information.
