Former NFL player Charles Tillman has a plan for life off the field. The former Chicago Bears cornerback is training to be a part of the Federal Bureau of Investigation, according the Chicago Tribune.

Tillman made history when he received the largest contract paid to a Bears cornerback, signing a six-year, $40.55 million extension in 2007. Tillman retired from the NFL in 2016 at the age of 36 after playing 12 seasons with the Chicago Bears and helping the Carolina Panthers make it to Super Bowl 50 after the 2015 season.

The Chicago Tribune reports that former Bears coach Dave Wannstedt said he was aware that Tillman was training for the FBI.

"First-class," Wannstedt said. "What a guy. Charles Tillman is as good as they come and I had a great time working with him."

Tillman already gives back to the children of the community through the his Charles Tillman Cornerstone Foundation, and he's also active in military endeavors. He was selected as the winner of the NFL's Salute to Service award in 2012.

Prospective candidates training to become special agents have to be at least 23 years old but younger than 37 at the time their appointment, according to FBI guidelines. Tillman will turn 37 in February.

"We don't speak about personnel matters," special agent Garrett Croon, a spokesman for the Chicago bureau, told the Tribune.

Previously, Tillman worked for Fox Sports on the "Fox NFL Kickoff" show during his first year of retirement. The football star has now decided to lend his skills to serving the community through law enforcement, but it's not that far-fetched considering his background. Tillman attended University of Louisiana-Lafayette where he received a bachelor's degree in criminal justice after growing up in a military family. So service is practically in his blood.
