Steelers linebacker James Harrison was talking to the media over the weekend. When asked about his health, specifically his back he said that he was going to have problems with it all year long and was going to have to play through the pain again just like he did in 2010. He mentioned having shooting pains down his leg on a regular basis.
Now he didn't miss any significant time last year and was able to play through the pain. He also had the 2 surgeries this offseason. He spent a lot of time in his hyperbaric chamber, getting acupuncture, and massages to help speed the healing. Let's face it though, when you start putting on the pads and going full speed it's going to be more present than it was while being able to sit at home for months.
Knowing Harrison, I wouldn't suspect he'll miss time because of it on Sunday afternoons but it still bears watching.
