Most hamstring injuries heal in weeks. For Cowboys quarterback Dak Prescott, it's been more than five months. It happened as he was throwing a pass during a Week 8 game at Atlanta, on November 3. As Chris Simms explained during Monday's PFT Live,

Prescott missed the remainder of the season after suffering a serious hamstring injury in a game on November 3 against the Atlanta Falcons. Now more than five months later, it's clear that the injury was more serious than previously expected.

The Dallas Cowboys traded for Joe Milton III last week to solidify their quarterback depth chart, but some are still treating the move as one that has them in position to replace Dak Prescott under center.
