A day ago, Bills coach Doug Marrone said quarterback Thad Lewis was 50/50.
Perhaps, the probability of Lewis playing against the Chiefs increased some now that he was able to return to practice. The Bills' official team site reports that Lewis was present for Friday's practice.
That's a good sign, but one that doesn't automatically mean Lewis is good to go. Lewis will need to come out of practice healthy without any setbacks to his rib injury.
