James Harrison will not retire, heading to Arizona to train

I decided to hold off on retirement, so it's time to pack up and head to AZ to start my training so I can be ready to play another year!

James Harrison has declared himself a free agent.

The Steelers outside linebacker declared via Instagram he will not retire from the NFL this year, a season after he returned to Pittsburgh in Week 4. He ended up being one of the Steelers' most effective pass rushers despite missing time with a knee injury toward the end of the year.

He is a free agent, and one the Steelers may consider bringing back, considering their lack of depth at the position. Jarvis Jones is the only signed outside linebacker with NFL experience on the roster.

Harrison finished the year with 5.5 sacks in 11 games, third-best on the team.

The timing of the announcement is interesting, considering outside linebacker prospects put on a clinic of athletic prowess Sunday at the 2015 NFL Scouting Combine. Harrison has been training, as he's depicted frequently on Instagram, but the Steelers may still need to address the position early in the draft.

He has an affinity for ex-Steelers defensive coordinator Dick LeBeau, who is now in Tennessee - another team in need of pass rush help.
