Thunder’s Russell Westbrook will sit out against Rockets

 Oklahoma City Thunder guard Russell Westbrook (0) reacts to a play in action against the San Antonio Spurs during the second quarter at Chesapeake Energy Arena. 

Russell Westbrook is just fine, but he won’t play Friday night in Houston.

Kendrick Perkins is just fine, but he won’t play either. Thabo Sefolosha is still recovering, and now Nick Collison may sit out Friday’s game, too.

Collison, who was injured last night after getting an elbow to the head from Jeff Ayers of San Antonio, was cleared to play, but the Thunder may have him sit for precautionary reasons. Collison did not suffer a concussion, according to team officials. He required four staples in his head.

The Thunder play the Rockets at 8:30 p.m.

Perkins played his first game since late February against the Spurs Thursday nightbut the team doesn’t want him playing back-to-back games. Same goes for Westbrook, who hasn’t played in both games when the team has played consecutive nights. Westbrook played Thursday against the Spurs and was not expected to play tonight against the Rockets.

Coach Scott Brooks said Sefolosha, who has been out the last month, is still recovering. Sefolosha has begun practicing with the team and could return as early as next week.

Steven Adams, Andre Roberson and Reggie Jackson will start in place of Perkins, Sefolosha and Westbrook.
