Every single day 1.2 million people witness the superhuman strength of  39-year-old James Harrison on Instagram. He has become just as famous for his grueling workouts off the field as his performance on it.

Shockingly, in between a clip of his weekly acupuncture session and a 700 pound deadlift last week, Harrison posted a collage of his sons announcing his retirement from the NFL.

Harrison’s caption read, “I’ve missed way too much for way too long. I’m done. Many thanks to my family, coaches, the fans, and everyone who played a role in my football life.”

Harrison signed with the Steelers in 2004 and managed to capture two Super Bowls. He racked   up 84.5 sacks, 34 forced fumbles and eight interceptions — none being more famous than the 100-yard interception return to close the first half in Super Bowl XLIII against the Cardinals. It still stands as the longest in Super Bowl history.

Throughout the course of his 15 seasons, Harrison earned five Pro Bowl selections, a 2008 Defensive Player of the Year award and has the most sacks in Steelers franchise history.

While he did most of his damage in Pittsburgh, Harrison also spent brief time in New England and Cincinnati.

He played sparingly in 2013 with the Bengals, prompting him to retire for the first time. It lasted all of 18 days before Harrison returned to Pittsburgh after injuries plagued the team’s linebacker group.

He made tremendous contributions up until last season, when younger draft picks like T.J. Watt transformed him from starter to spectator.

Harrison ended up seeing a lot more action in New England than many had anticipated. After having played just 40 snaps over 14 games with the Steelers last season, Harrison was on the field for 69 snaps in the Super Bowl.

Now the only question remaining lies in the hands of the Steelers front office. Will Harrison’s incredible stats overpower his traitorous choices and allow him to join icons like Joey Porter, Franco Harris, and Santonio Holmes as one of the few players to sign one-day contracts and “retire a Steeler.”  

At the end of the day, Harrison leaves the league with an inspirational story full of determination and passion for his craft. Fans shouldn’t fault him for wanting to play when he knew his time left was limited. To hold the franchise sack record over Steelers like Mean Joe Greene , L.C. Greenwood, and Dwight White is truly remarkable. He was a true competitor  and if he was cut open, he would bleed black and gold. Pittsburgh is where he belongs and he should come back home before his next stop at Canton.
