Dolphins running back Reggie Bush (knee) did not practice Wednesday as the team prepares for Week 4 at Arizona. The Palm Beach Post reports Bush was working with a trainer Wednesday. He was riding a stationary bike and stretched with the team. The Miami Herald reports Bush will practice once the swelling and stiffness is gone from his left knee. "If it was up to me I'd be playing no matter what. But it's up to the coaches. We got time for that. It's a long week," Bush said, per the Sun-Sentinel. "We have depth at the running back position, guys who can step in there and make plays."
