Donatas Motiejunas won't report to the Houston Rockets because of a difference of nearly $6 million from the offer sheet he signed with the Brooklyn Nets.

Motiejunas signed a four-year, $37 million offer sheet with the Nets that the Rockets matched. The Rockets only had to match the principal terms of the offer sheet of $31 million. 

The $6 million difference was to be paid to Motiejunas via incentive clauses if he played for the Nets.

Houston's options are to keep their first-refusal exercise notice open and wait for Motiejunas to report. If he doesn't report, Houston can pull the offer Thursday and Motiejunas would become a restricted free agent. If they don't pull the offer, it would expire automatically March 1.
