The backup quarterback spot for the Dallas Cowboys is an important one given the injury history of Dak Prescott, but Joe Milton III and Will Grier have not been particularly impressive during the preseason.

ARLINGTON, Texas -- The Dallas Cowboys knew they were getting a young backup quarterback that needed development when they acquired Joe Milton in a trade from the New England Patriots this offseason.

For the second straight preseason game, the former New England Patriots backup quarterback was a disappointment. This time, it was a 31-13 loss to the Baltimore Ravens where he completed 50% of his passes, threw a pick and was sacked for a safety.

Undrafted rookie cornerback Keyon Martin dials up the pressure and sacks Cowboys quarterback Joe Milton for a safety.
