Serge Ibaka

The injury-plagued Oklahoma City Thunder may be out another key player, as forward Serge Ibaka will undergo a knee procedure to address persistent soreness, reports ESPN.

It’s unclear how long Ibaka will be sidelined following the surgery.

He’s been out of the line-up for the Thunder’s past two games with knee soreness. The team has not confirmed the surgery, but instead, have only said he will see a specialist for further evaluation.

The Thunder’s injury issues have plagued them throughout the season, with Kevin Durant missing 39 games and Russell Westbrook missing 15.

OKC is currently 37-29, just a game ahead of the New Orleans Pelicans for the Western Conference’s eighth seed.
