The Utah Jazz said they will “thoroughly investigate” an allegation from former NBA player Elijah Millsap that longtime team executive Dennis Lindsey directed a bigoted statement toward him during an end-of-season exit interview in 2015.

Millsap, the brother of former Jazz standout and current Denver forward Paul Millsap, made the allegation in a tweet on Wednesday.

Millsap alleged that Lindsey, then the team’s general manager, said “if u say one more word, I’ll cut your Black ass and send you back to Louisiana.”

Lindsey, now the team’s executive vice president, has denied saying that.
