"Right now we're not concerned because it's not in the hip joint, it's more in the muscle," manager Don Wakamatsu said Wednesday. "I think it's just really about being on the mound again. This is more muscle soreness. He had some stiffness in there about four days ago, and we thought it was best at this point to rest it a little bit. It might be a blessing to get his arm a little bit of a break, too."
