The Las Vegas Raiders have just released Damon Arnette ... after the former first-round pick was seen on video waving around firearms and threatening to kill somebody.
The footage of the 25-year-old -- who was taken #19 overall in the 2020 NFL Draft -- was posted on social media last week and eventually went viral over the weekend.
It featured Arnette brandishing three different kinds of guns ... all while telling someone, "I swear to God I will kill you, n****. On everything I love, I will kill you, n****. You talking crazy.
