Harrison has decided he wants to play one more season, the Pittsburgh Post-Gazette reports. "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," Harrison wrote on Twitter and Instagram Sunday. The ball is in the Steelers' hands now, as Harrison becomes an unrestricted free agent March 10 if Pittsburgh does not sign him before then. Currently, Jarvis Jones is the only outside linebacker with experience under contract.
