James Harrison retires a second time. This seems to be the official end.
The 39-year-old runner announced on Instagram on Monday morning that he calls it a race.
"I've been missing too much for too long," Harrison wrote. "I finished, thank you very much to my family, to the coaches, to the fans and to all those who played a role in my football life."
Harrison, who turns 40 next month, denied his retirement in 2014, when he returned to the Steelers less than three weeks after retiring.
If this is really the end, the pass-rusher concludes an amazing trip through the NFL.
The Kent State product was not included in the draft in 2002, and most teams believed it was too small to be a pass rusher. To prove himself, Harrison played for NFL Europe's Rhein Fire in 2003. Eventually he became NFL Defensive Player of the Year, five-time Bowler winner and two-time All-Pro first player in Pittsburgh.
As a relentless racer with the brute strength of 45 grizzly bears and a good first step, Harrison worked to become the all-time looting leader of the Pittsburgh Steelers, with 80.5.
Harrison played his first 10 seasons in the NFL with the Steelers before a sabbatical with the Cincinnati Bengals (where he detested and provoked Hard Knocks cameras). The linebacker then returned to Pittsburgh in 2014, where he played until he was cut midway through last season. Harrison signed with rival New England Patriots for the final straight. The defeat of Super Bowl LII of the Pats began.
Harrison will be remembered as one of the Steelers' all-time greats who worked ruthlessly to transform his forgotten camp guest career into a dominant pass runner at his best.
