Former NFL star cornerback Charles "Peanut" Tillman is reportedly training to become an FBI agent.

The Chicago Tribune reported today that Tillman, who spent most of his career with the Chicago Bears and played last in 2015 with the Carolina Panthers, is in training at Quantico.

Tillman was renowned for his ability to jar the ball loose from offensive players with the "Peanut Punch" and forced 44 fumbles during his career, nearly twice as many as the next closest defensive back during his time in the league. Tillman was a two-time Pro Bowl selection and was named the NFL Walter Payton Man of the Year in 2013 for his philanthropic efforts.

Tillman earned a bachelor's degree in criminal justice from the University of Louisiana-Lafayette before the Bears drafted him in the second round in 2003. He grew up in a military family — his father, Donald Tillman Jr., was a sergeant in the Army — and attended 11 schools from kindergarten through 12th grade.

Tillman not only supports children's charities through his Charles Tillman Cornerstone Foundation, he also has long been active in military endeavors. In 2010, he spent eight days on a USO tour visit with troops in Iraq and Kuwait. He was selected as the winner of the NFL's Salute to Service award in 2012.
