Report: Cowboys, Lawrence won't reach long-term deal before tag deadline

The Dallas Cowboys won't reach a long-term deal with defensive end Demarcus Lawrence before Tuesday's franchise tag deadline, a source told ESPN's Adam Schefter.

Cowboys COO Stephen Jones has said the team doesn't intend to let the pass-rusher out of the building and is prepared to use the franchise tag on the four-year pro if necessary.

Lawrence blew onto the scene last season with 14.5 sacks - the second-best mark in the league. The Cowboys can ill afford to lose their top pass-rushing talent.
