Utah Jazz vice president Dennis Lindsey denied an assertion by former player Elijah Millsap that he used racist language in 2015.
Millsap tweeted Wednesday that Lindsey, in the company of head coach Quin Snyder, told the player during an exit interview, "If you say one more word, I'll cut your Black ass and send you back to Louisiana."
"I categorically deny making that statement," Lindsey told the Deseret News' Sarah Todd.
The NBA has launched an investigation, with which the Jazz say they're fully cooperating.
"The Jazz organization has zero tolerance for discriminatory behavior of any kind," the team said in a statement, according to ESPN's Adrian Wojnarowski. "We take these matters seriously. We have proactively engaged outside counsel to work in coordination with the NBA to thoroughly investigate this matter.
"We seek a comprehensive and unbiased review of the situation."
Snyder insisted Wednesday that he doesn't recall the incident.
"Honestly, I don't remember the conversation," Snyder said. "I can't fathom Dennis saying something like that."
Millsap suited up for the Jazz from 2014-16. He's the younger brother of four-time All-Star Paul Millsap, who played in Utah from 2006-13.
