The official start to the 2019 Dallas Cowboys season begins on Saturday with a preseason game against the San Francisco 49ers. Both teams, along with the other thirty NFL teams, will carry rosters of 90 players through all four preseason games.
Some of you may remember the days of cutting the roster to 75 prior to the last preseason game and then to 53 immediately following. As outlined in this ESPN.com update, that changed back in 2017, and now young players have longer to impress coaches and earn a roster spot or land on the practice squad.
