Rodney Harrison says he’s ‘scared to death’ after a career filled with concussions

After suffering an estimated 20 concussions over his 15-year pro career, Rodney Harrison now says he's "scared to death" about the future of his health in upcoming years.

In an emotional interview on the upcoming Costas Tonight Super Bowl special, the former all-pro safety for the San Diego Chargers and New England Patriots says he now experiences symptoms of loneliness, isolation and anxiety. Harrison believes the NFL did not do enough to educate players about brain trauma during his career and says that he never even heard the word "concussion" mentioned by teams for his first five or six seasons in the league.

Harrison was known for a hard-hitting style that earned him over $200,000 in fines over his career and often earned him the label of a "dirty" player. But with his career now over, the 40-year-old father of four is speaking out with more attention being paid attention to the brain trauma issue after the recent suicides of former players Dave Duerson and Junior Seau.

"A lot of these players are really really suffering, Bob," Harrison said to Costas. "And this stuff is for real because I'm experiencing it now. I'm scared to death. I have four kids, I have a beautiful wife and I'm scared to death what might happen to me 10 or 15 years from now."
