Priest Holmes went through a full practice Wednesday, a giant step toward what could be turning into one of the NFL's great comebacks. Now 34 and out of football since suffering neck and spinal injuries two years ago, Holmes was cleared to practice for the first time since he shocked the Chiefs last summer and showed up at training camp. He's been working out diligently and trimming away the 15 or so pounds he gained while staying home the previous 22 months, hardly going near a football field.
