Former Chicago Bears defensive back Charles "Peanut" Tillman has made some appearances on tv as an analyst in his post-NFL life, but he's currently training for a completely different line of work.

According to Brad Biggs of the Chicago Tribune, Peanut Tillman hopes to land a job with the Federal Bureau of Investigation and has begun training to make that happen. Although, as the Chicago Tribune reports, Tillman has a limited window to make things work.

"FBI guidelines mandate prospective candidates for hiring as a special agent must be at least 23 years old but younger than 37 at the time of appointment. Tillman turns 37 on February 23."

Before being drafted by the Chicago Bears in the second round of the 2003 NFL Draft, Tillman received a bachelor's degree in criminal justice from the University of Louisiana-Lafayette. He also grew up with a military background - his father was a sergeant in the United States Army. Additionally, his uncle was in the Army for 30 years and his mother-in-law is a Marine.

In an interview with Make It Better Magazine last July, Tillman spoke about his appreciation for law enforcement and his interest in helping out.

Per Make It Better,

"So I'm all about our military and supporting our men and women in uniform," he said. "[I'm also interested in] helping police officers and law enforcement, I'm big into that. A lot of my friends are law enforcement officers, and [I like to] support them as well."

Tillman retired as a member of the Carolina Panthers after the 2015 season, but he spent 12 of his 13 years in the NFL as a member of the Bears.  In 2013, Tillman received the Walter Payton NFL Man of the Year Award, which recognizes one NFL player per year for his excellence on and off the field. He worked for Fox Sports on the "Fox NFL Kickoff" show last season in his first year of retirement, but is now transitioning into what could be a new role with the FBI.
