'NFL Characters Unite' Trailer: Defensive Ends Taking On Bullying (Exclusive Video)

The fourth annual anti-bullying documentary will feature the Buffalo Bills' Mario Williams and the Eagles' Darren Sproles.

NFL Characters Unite is an annual anti-bullying documentary from the NFL and producer Charlie Ebersol that shows even the biggest guys on the field used to get knocked down in school.

The trailer, which The Hollywood Reporter debuts exclusively, sees Charles Tillman, the cornerback for the Chicago Bears, confessing, "I didn't really fit in a lot of places. I was labeled as the geek, the loser." Oakland Raiders defensive end Justin Tuck admits that he was bullied because he "excelled in school."

This is the fourth incarnation of NFL Characters Unite. This year, Mario Williams (Buffalo Bills), Jamaal Charles (Kansas City Chiefs), Richard Sherman (Seattle Seahawks) and Darren Sproles (Philadelphia Eagles) also share their personal stories of bullying and prejudice while teaching others that they can overcome their own adversity.

Says Ebersol of producing the special for the past four years: "I have learned that there are few things as powerful as shared experience. These past four years have been a shining example of the power of superstars showing kids in need that they were just like them and that with hope, determination and faith, the 'expected path' can be transformed into the 'dream path.' This show is as much about the American dream as it is about ending discrimination, hate and bullying."

Past participants have included Houston Texans defensive end J.J. Watt as well as former Indianapolis Colts head coach Tony Dungy, among others.

NFL Characters Unite will air Feb. 6 on USA.
