Four 49ers to watch in tonight's NFL preseason opener vs. Cowboys

The first exhibition game of the season is rarely about the starters, and 49ers' summer unveiling will be no exception. Quarterback Jimmy Garoppolo and the 49ers' healthy starters on both sides of the ball are expected to see limited action – one series or two -- Thursday night when the pre-cuts version of the Dallas Cowboys come to Levi's Stadium. It will be a notable evening for many of the team's young players who are either battling for spots on the roster or roles for the regular season.
