Ausar Walcott may not be as famous as Aaron Hernandez, but he’s in a lot of trouble, too. The Cleveland Browns’ rookie linebacker turned himself in to Passaic (N.J.) police on Tuesday night to face charges of attempted murder. Walcott, who is from Hackensack, allegedly punched Derrick Jones, 24, in the head outside The Palace Gentleman’s Club early on Sunday morning. Jones, who lives in Manhattan, was rushed to Harlem Hospital Center. Jones remained hospitalized and in critical condition on Wednesday, authorities said.
