Linebacker James Harrison, who turns 40 next month, announced his retirement on Instagram.  

Although he proved during the Patriots Super Bowl run that he can still contribute, Harrison says he’s missed way too much, for way too long.

I’ve missed way too much for way too long…and I’m done.Many thanks to my family, coaches, the fans, and everyone who played a role in my football life.#2ndAndFinalRetirement#HarrisonFamilyValues#BlessedAndHighlyFavored #GodsPlan

From the looks of it, Harrison is still planning to spend a lot of time in the gym.  Retirement doesn’t mean he’s hanging up his gym sweats just yet. 

Maybe he’ll be starting a second career as a bodybuilder.
