St. Louis Rams running back Tre Mason has been a full participant in practice this week and says he'll be ready to play Week 2 after sitting out Week 1. He says he was very close on Sunday but now he's 100 percent. "(It was) kind of just bad luck kind of thing," Mason said. "It doesn't really happen much but soft tissue injuries, they just kind of nag a little bit but I'm a pretty quick healer. I try to stay on top of things but I'm ready to go … I was close. I wasn't 100 percent.
