Here’s the Houston Chronicle with a report on Rockets center Omer Asik, who has been on the trading block for much of this season:

Omer Asik struggles with recovery from knee injury

The Rockets were not only still without center Omer Asik – and will not have him for the immediate future at least – they were also still unsure why he has been unable to make improvement from his injury.

Asik has repeatedly been able to make strides and greatly increase workouts, but each time he seems close to being able to return, the swelling in his knee returns. The Rockets sent him for the more detailed MRI last week, but it showed no damage to the knee. They have sent those test results to another expert, hoping to get a better idea of why the problem remains so persistent.

Asik initially went out after a bruised thigh Dec. 2. Swelling developed in his knee soon after, forcing him to miss the next 11 games, an absence made an even greater issue with backup center Greg Smith also out.
