Jeff Niemann was pushed back from Thursday's start due to soreness in his upper back. Niemann has had back issues before, missing six weeks earlier this season with a lower-back strain. He says his back didn't bother him during his start last week, but that it stiffened up on him the next day. Niemann insists he'll be fine to start Saturday, though. "I'm going out there, period," Niemann said. "That's gonna happen."
