According to a report from NFL Network insider Ian Rapoport, the injury that is keeping Kansas City Chiefs defensive end Frank Clark out of Sunday night’s game against the Green Bay Packers is considered “week-to-week.”
#Chiefs pass-rusher Frank Clark, out tonight with a neck injury, is considered week-to-week, source said. That means he could be out more than this week, though KC is hopeful it’s not long-term. Either way, he’s been battling this and somehow has been playing.

Reading between the lines of Rapoport’s tweet (“he’s been battling this and somehow has been playing”), we could infer that Clark’s neck injury has been an issue for an unknown period of time — but one that extends to before the Broncos game in Denver.
