Dyson Daniels has fouled out after a lengthy review as Atlanta fell short of a late comeback win against Cleveland to remain in NBA post-season limbo.
But there was no stopping Oklahoma City, who for the third straight season finished as the No.1 seed after their 128-110 victory over the Los Angeles Clippers.
The Hawks lost 122-116 to the Cavaliers at home on Wednesday (Thursday AEST), Cleveland's (51-29) fourth straight win meaning they can finish no lower than fourth in the Eastern Conference.
