The Dallas Cowboys are pushing to sign Dak Prescott to a long-term extension before the March 10th franchise tag deadline.

The Cowboys are expected to use the franchise tag on Prescott if they're unable to sign him to an extension. The Cowboys, however, could use the tag on Amari Cooper or Byron Jones if they extend Prescott before the deadline. 

The Cowboys and Prescott have had their talks stall in recent weeks.
