Charles suffered a high ankle sprain Sunday, according to Chiefs' coach Andy Reid, Lindsey Jones of USA Today reports.

Analysis:

Charles' sprain was initially thought to be mild, but Reid disclosing his star running back actually sustained a high ankle sprain is certainly of concern. The variety of sprain typically forces players to miss time, putting Charles' Week 3 status moving forward in question. While a timetable for his return has not yet been outlined, it appears as though Knile Davis could be in line for an extended role in the Chiefs' offense Sunday against the Dolphins.
