PITTSBURGH — James Harrison isn’t preparing for a second retirement ceremony.

The 36-year-old Harrison posted an Instagram photo on Sunday night saying he was heading to Arizona to train, as he does during the winter. Harrison will become a free agent next month after spending 2014 with the Pittsburgh Steelers following a brief 18-day retirement.

The five-time Pro Bowler spent a month getting in shape before showing flashes of his former brilliance. Harrison finished with 5½ sacks in 11 games for the Steelers, who went 11-5 and won the AFC North title.

Steelers general manager Kevin Colbert said earlier this month the team wasn’t ruling out a return by Harrison. Pittsburgh will be searching for depth at outside linebacker.
