Joel Embiid made headlines by getting into an altercation with a Philadelphia reporter on Saturday night after the Sixers lost to the Memphis Grizzlies. Philadelphia Inquirer columnist Marcus Hayes got a push from Embiid for the way he wrote about Embiid’s brother and son in a recent column criticizing the former MVP for not being on the court this season.

On Sunday, Hayes gave his side of the story to fellow Inquirer reporter Gina Mizell, saying that 76ers president of basketball operations Daryl Morey apologized to him for Embiid’s actions and called the situation “unacceptable”. Of the researcher:

“After (the incident), Hayes said he was escorted to a meeting with Sixers president of basketball operations Daryl Morey and general manager Elton Brand,” Mizell wrote. “Hayes said Morey and Brand ‘apologized for the incident, expressed regret for what had happened, and asked me for my side of the story…They agreed that Embiid’s actions were unacceptable.'”

Mizell also noted that Embiid’s “open hand made contact with Hayes’ neck and collarbone.”

The NBA announced an investigation into the matter and the 76ers confirmed that the organization will cooperate fully. Philadelphia plays next Monday night against the Phoenix Suns.
