'Not every injured Bill was back on the field, though. Safety Corey Graham, defensive tackle Kyle Williams (knee) and wide receiver Percy Harvin (hip/personal) all missed practice Monday. Graham and Williams were in the weight room during practice, but Harvin wasn't spotted during the portion of practice open to the media. According to Rand Getlin of NFL.com, Harvin is meeting with the Bills to have his hip injury evaluated and the team is taking the situation one day at a time.'
