The San Francisco 49ers open their preseason this Saturday against the Houston Texans, and that means we start to see how the bottom of the depth chart might shape up. A lot of rookies and other young players will be looking to take advantage of their first opportunity at real NFL action. Some will get big chances in the middle parts of the game, while others will be "relegated" to the fourth quarter.
One player that most everybody will be watching closely is Jarryd Hayne. The running back and return man will step on the field for his first real organized football following a career in Rugby League.
