The Dallas Cowboys put a franchise tag on Dak Prescott back in March.
The player had refused to sign the tag in efforts to continue negotiating a long term deal with The Cowboys.
Dak Prescott finally signed the 31.4 million dollar tag this morning.

By signing, the player is now required to report to training and participate in all NFL events.
Prescott and The Dallas Cowboys have been negotiating a long term deal.

They now have 23 days left to reach an agreement before the July 15th deadline.
