A former Hackensack High School football star who was signed by the Cleveland Browns last month was arrested Tuesday and charged with attempted murder for allegedly punching a man outside a bar in Passaic, authorities said.

Ausar Walcott, 23, punched the man in the head outside The Palace Gentlemen’s Club on Main Avenue around 3 a.m. Sunday, said Detective Andrew White of the Passaic police.

Friends of the victim, Derrick Jones, 24, who lives in New York City, took him by car to the Harlem Hospital Center in Manhattan shortly after the assault, White said. He remained hospitalized in critical condition on Tuesday, White said.

Walcott, who told police he has been living with a friend in Maywood, was charged with first-degree attempted murder, second-degree aggravated assault and third degree endangering an injured victim, White said. He was arrested Tuesday morning after he turned himself in to police, and his bail was set at $500,000 cash, White said. He was scheduled to be sent to the Passaic County Jail in Paterson on Tuesday evening.

Jones’ aunt called police to report the assault later on Sunday, and Walcott was identified as a suspect after an investigation conducted by Detective Sgt. Roy Bordamonte and detectives James Lane, Paul Slater and Alexis Flores, White said.

The Browns announced that they had signed Walcott and four other players in a posting on their website on May 13. They issued a brief statement on Tuesday afternoon saying the team was “aware of the situation.”
