Evan Holyfield clattered Charles Stanford to the canvas in the second round of their fight to score a knockout in front of his legendary father on Saturday night.
Evander Holyfield, one of just three men to become world champion at cruiserweight and heavyweight and the long-time rival of Mike Tyson, watched from ringside as his son impressed again.
Evan, 24, stung Stanford with a left hook then heavily dropped him with a right hand shortly into the second round in his home city of Atlanta.
He is unbeaten in eight fights, with six knockouts, in the super-welterweight division.
He celebrated with his father who, aged 58, was back in the ring earlier this year but was beaten inside a round by former UFC great Vitor Belfort.
Xander Zayas also recorded victory with a fourth-round stoppage against Dan Karpency.
Zayas, a 19-year-old Puerto Rican talent, delivered enough hurtful blows to convince his opponent to be withdrawn by his corner.
