Veteran NBA referee Eric Lewis has retired three months after the league began an investigation into “burner” social media accounts that vociferously defended his officiating.

The NBA announced Lewis’ retirement Wednesday, and said in a statement: “In light of his decision, the NBA’s investigation into social media activity has been closed.”

The Twitter account @CuttliffBlair, with the name username “Blair Cuttliff,” had one response after another that had seemed to seek out any criticism of how Lewis was doing his job with the NBA.

The account, which was opened in 2015, had zero followers eight years later.

Lewis was repeatedly accused by various fan bases of having a bias for the Celtics.

One account claimed the Celtics had a 54-29 record in games officiated by Lewis, saying the metric is “f–king insane” and “smells like CORRUPTION”.

The burner account responded: “Not sure if thats true either. Pretty sure there are other refs with similar stats with top teams. Smells like nothing to sniff.”

Another user asked “Is the league this stupid??!??” to allow Lewis to officiate Celtics games, to which the burner responded, “Naw twitter is because they believe this bs,” adding three laughing emojis.

The account was following five other users on the social media app, including the account George Mason’s women’s basketball team, where Lewis’ wife, Vanessa Blair-Lewis, is head coach.

NBA officials are not allowed to publicly comment on their calls without authorization of the league.

The NBA’s investigation of Lewis was first reported in May by veteran basketball writer Marc Stein.

Lewis had been an NBA official for nearly 20 years, and was tabbed as a referee for multiple playoff games this past season, including the Celtics’ win over the Sixers in Game 7 of the Eastern Conference semifinals.

Lewis was not selected as an official for the NBA Finals as the investigation was ongoing.
