Harvin (illness) was not at practice Thursday, Chris Brown of the Bills' official site reports.

With Harvin still dealing with migraines, his status for Sunday's game against the Raiders looks cloudy. Since Robert Woods is also very iffy for the contest, it looks like the Bills' wideout corps will once again be taxed in Week 13. On the plus side, Sammy Watkins was spotted on the practice field Thursday.
