Commanding and fearless NFL powerhouse Shawne Merriman never met a quarterback he couldn't sack. Largely regarded as one of the greatest defensive players in the league's history, this former first-round draft pick and three-time Pro-Bowl and All-Pro linebacker is known as 'Lights Out' to the world, a nickname originating from his unmatched power on the field and ability to ignite his teammates while intimidating the opposition. Merriman's excellence and drive for success did not subside when he exited the stadium. His undeniable tenacity and dedication has led to international success in both business and entertainment. It is not only Merriman's strength and performance on the field that makes him so magnetic. His fervent desire to give back to his community and inherent entrepreneurial spirit are what make him a truly remarkable man. As a child, Merriman was the victim of two house fires, and he was homeless as a result. Now a father himself, he has worked tirelessly in an effort to give back to his community and assist homeless children and families in need. Merriman is teaming up with The Challenge to benefit his charity, the Lights On Foundation.
