It seems that Le'Veon Bell's time with the black and gold may be coming to an end.The Steelers and Bell failed to reach agreement on a long-term contract before Monday's franchise tag deadline. Bell's agent, Adisa Bakari, told ESPN's Adam Schefter that "this now likely will be Le'Veon's last season as a Steeler."Bell must now play the 2018 season on the franchise tag, which the Steelers placed on him for the second year in a row. He would then become an unrestricted free agent who can sign with Pittsburgh or any other NFL team.Steelers general manager Kevin Colbert released the following statement Monday:"Even though we could not reach a long-term contract agreement with Le'Veon Bell, we are excited he will be with the team in 2018. We worked hard to find common ground, but we were unable to accomplish that prior to today's deadline. Le'Veon will play this season under the exclusive franchise tag designation.After the 2018 season is completed, we again will attempt to work out a long-term contract with Le'Veon in hope that he will continue his career with the Pittsburgh Steelers."Bell tweeted this message shortly after the deadline passed:"to all my Steeler fans, my desire always has been to retire a Steeler...both sides worked extremely hard today to make that happen, but the NFL is a hard business at times...to the fans that had hope, I’m sorry we let youu down but trust me, 2018 will be my best season to date..."
