The Pittsburgh Steelers placed the franchise tag on running back Le'Veon Bell for the second consecutive year.
The move, which was expected, was reported by the NFL Network and confirmed by the Pittsburgh Post-Gazette just over an hour before Tuesday's 4 p.m. ET deadline for teams to issue tags.
Should he sign the agreement, Bell would receive $14.544 million in 2018. Bell sat out offseason workouts a year ago before signing his franchise contract in 2017.
Bell, 26, was optimistic a long-term deal could be struck and the sides have until July 16 to do so. He told ESPN on Monday that the two sides were "not coming to a number we both agree on."
During Super Bowl week, Bell said that the contract talks "were all about the guarantees" and hinted that it would require more than $30 million guaranteed to get it done.
Bell has threatened to retire from football unless he gets a contract that tops the three-year, $42 million deal that he turned down last year.
