In a recent interview, Troy Polamalu admitted that playing football is always risky.
The Steelers safety has a history of giving and receiving hard hits.
"People are paralyzed on a football field," he told the Pittsburgh Tribune-Review.
"People die ... You just never know when it's going to be your last moment. I was the kind of guy who would never talk to my wife on game day. Now I'm the guy who's like, 'I love you.' I want my children to know I love them because I don't know what's going to happen out there. I'm not trying to play the martyr here. I love football. It's something we choose to do. We all know how much of a gamble it is to play this game."
