Per ESPN's Jeremy Fowler, Bell intends to be ready when the Steelers open the regular season, and "missing games over the contract would be a shock."
Bell and the Steelers failed to come to terms on a long-term contract before Monday's deadline. The 26-year-old will play under the one-year franchise tag for the second straight season, though he still has yet to sign that agreement worth $14.544 million.
Per NFL.com's Ian Rapoport, Pittsburgh's final offer to Bell was $70 million over five years.
Adisa Bakari, Bell's agent, told ESPN's Adam Schefter, "This now likely will [be] Le'Veon's last season as a Steeler."
After receiving the franchise tag last year, Bell held out during training camp before rejoining the Steelers on Sept. 1, nine days before the season began. He overcame a slow start to finish with 1,946 yards from scrimmage and tied his career high with 11 total touchdowns.
The Steelers open the 2018 season Sept. 9 against the Cleveland Browns at FirstEnergy Stadium.
