Dallas Cowboys Injury News: Dez Bryant, Byron Jones, Others Out For Preseason Game Against 49ers?

The Dallas Cowboys have high hopes for the 2015 NFL season, but the year hasn't exactly gotten off to the start that the team was looking for. Dallas suffered a loss in its first exhibition game, and they are dealing with several injuries ahead of Week 2 of the preseason. When the Cowboys visit the San Francisco 49ers on Sunday, they could be without a few top players. Cornerback and running back are the two positions that have been hit particularly hard with the injury bug.
