Who is Jaylen Brown’s dad? All about Marcelles Brown's arrest in Vegas stabbing

Quenton Marselles Brown, the father of Boston Celtics star and 2024 NBA Finals MVP Jaylen Brown, was taken into custody in Las Vegas on charges of attempted murder after a violent altercation that happened on Wednesday, August 20.

The Las Vegas Metropolitan Police Department report stated that Brown and the other vehicle's driver were in a parking lot when Brown allegedly dinged the other vehicle. Brown and the other driver began to dispute over the issue, which then escalated into a physical confrontation. Witnesses told police that Brown produced a knife and stabbed the victim multiple times.

While many fans recognize Jaylen Brown as one of the successful stars in the NBA, fewer people know who his father is. Marselles Brown, who is sometimes known as Quenton Brown, was a professional heavyweight boxer.

According to a report by Slam, at seven feet tall, Marselles Brown had a remarkable career as a boxer and finished it with a record of 33-18-1. He also won the World Boxing Union (WBU) World Champion Title in 2016.

Marselles said in interviews that he came out of retirement to inspire his kids because he wanted them to see perseverance and resiliency. He would often talk about Jalen with pride, and also his older brother, and emphasize the value of hard work and focus that would translate to their sports and life.

 "I am extremely proud of both my sons. I am especially proud of Jaylen. He is an extraordinary athlete and very smart," he said in a 2016 interview with boxing247.com
