Texans running back Arian Foster will be ready to play in Week 1 of the regular season. Foster strained his left hamstring on Saturday night in a preseason game against the 49ers, but the NFL's reigning rushing champion says the injury in mild and improving. "I'm okay," Foster said. "It's a lot better than I thought it was. I'm already jogging." Foster's strained hamstring that cost him two weeks of camp is worse than the one he suffered Saturday. "It's never a good thing to have experience with hamstring problems, but, unfortunately, with my track record, I do," he said. "It was just a mild strain. It feels good."
