Four 49ers players to watch in Saturday's preseason game vs. Texans

When the 49ers face the Houston Texans on Saturday night in the second preseason game for both teams, it will represent the final setting of three important days of work in the Lone Star State. It's another opportunity to make favorable impressions after two fruitful joint practices on Wednesday and Thursday. "We just ran about 150 plays in two days (of practices) in 100-degree heat," Texans coach Bill O'Brien said.
