Eric Lewis was not selected among one of the 12 referees who will work the NBA Finals while the league investigates whether he used a Twitter account to defend himself.
Lewis had been chosen to work the Finals in each of the past four seasons.
It has not been determined if Lewis was using the account, which utilizes the name "blair cuttliff." The account was deactivated briefly last week but was active again Wednesday evening.
"Regarding Eric Lewis and the social media posts, we are continuing to review the matter and he will not be working the Finals," NBA spokesman Mike Bass said Thursday.
