Police say the two began an argument inside Thursday night and then fought outside Bully's Sports Bar & Grill on Sierra Highlands Drive.
The victim was stabbed several times and pronounced dead after being taken to a hospital. His name was withheld pending notification of family members.
48-year-old Michael Vinci of Reno was later arrested after leaving the scene with a woman and booked into the Washoe County jail.
An investigation continues into the 8:15 p.m. fight.
