49ers Give CB Cox a Second Chance Cornerback Perrish Cox is getting a fresh start with the San Francisco 49ers, signing a two-year contract more than a week after being acquitted on sexual assault charges in Colorado. San Francisco announced the deal on the first day of NFL free agency Tuesday, a day after signing wide receiver Randy Moss to give him a second chance. The 25-year-old Cox didn't play in 2011, spending time with his family in Waco, Texas. He was accused of sexually assaulting a woman at his apartment in September 2010 after a night of partying. The former Broncos defensive back says he appreciates the opportunity. General manager Trent Baalke says the team is "confident that Perrish will be a positive contributor to the 49ers, as well as our community."
