Bills DE Chris Kelsay aggravated his neck injury in Sunday's loss, and "could miss some time." Kelsay was suiting up Sunday for the first time since Week 9. If "some time" is anything more than 1-2 games, he could be a candidate for injured reserve. Kelsay has been starting in the absence of RE Mark Anderson (knee surgery). Anderson will likely be sidelined at least 1-2 more weeks.
