Adams NBA career has been plagued with injuries and earlier this year he entered the competition's concussion protocol programme after hitting the court hard in a match against the Clippers.
Today's game was OKC's first of the pre-season.
The last time these two teams were on the same court it marked the end of the OKC Thunder season.
Both squads entered today's match with vastly restructured rosters. Houston underwent a massive roster shuffle with eight players exiting who contributed to the team last season.
Most of those departed either as part of the blockbuster trade to acquire Chris Paul or were released to accommodate salary space for Paul and other free agent signings.
Moreover, ownership has changed with Tilman Fertitta buying the team.
