"His agent needs to be fired."
Ex-Dallas Cowboys player Jason Hatcher just went off on the Dak Prescott injury situation -- saying the QB's advisors should be ASHAMED for allowing him to play without a longterm contract.
"First of all, I wanna just send my prayers out to Dak," Hatcher said ... "[but] that young man and the team around him should have never allowed him to ever touch the field if he didn't have a longterm deal."
Prescott tried renegotiating a longterm deal with the Cowboys during the offseason, but ultimately agreed to play on a 1-year franchise tag deal that paid him $31.
