Lane Kiffin move around the practice field slowly, instead of the way he usually pops from drill to drill. When the Raiders coach had something to tell one of his players, he'd call him aside and do it face-to-face instead of yelling it out for all to hear. Kiffin was back at practice Wednesday after missing the previous two days while being hospitalized for a viral infection. But it was a very different Kiffin, who was under orders from his doctor not to yell or exert energy.
