Analysis:

The Rockets recently reacquired Motiejunas from the Pistons after last week's trade was voided due to concerns over the big man's surgically-repaired back. Until the Rockets get some clarification on the extent of Motiejunas' setback, it will be difficult to predict when he'll be able to return.
