According to a report in the Dallas Morning News on Monday, the Cowboys will use the franchise tag on Lawrence in a move that was expected to happen. Tuesday is the first day teams can use the franchise tag.
Dallas plans to make the move by March 6, which is the last day the franchise tag option can be used.
The sides, which have until July 16 to reach a long-term deal, are expected to meet next week during the NFL Scouting Combine in Indianapolis to begin discussing a long-term deal.
Using the franchise tag on Lawrence would give him a one-year deal worth $17.5 million, but both sides have reiterated their desire for a long-term contract.
Lawrence, 25, started every game last season and finished with 14.5 sacks, tying him with Jacksonville's Calais Campbell for second in the league. He recorded 7.5 sacks in Dallas' first three games and had a sack in the first seven games to earn a Pro Bowl berth.
Lawrence's breakout season occurred after he underwent back surgery for the second straight offseason in Jan. 2017.
The Cowboys drafted Lawrence with their second-round pick in 2014 out of Boise State. In four seasons with the Cowboys, Lawrence has 23.5 sacks and 133 tackles.
