According to NFL Network’s Ian Rapoport, Kansas City Chiefs running back Isiah Pacheco suffered a fractured fibula during Sunday’s 26-25 victory over the Cincinnati Bengals, which will force him to miss significant time.

How much time? Rapoport’s initial report didn’t say. But ESPN’s Adam Schefter reported that he will be out for at least four weeks.

On Monday afternoon, ESPN’s Jeremy Fowler revealed a timeline for Pacheco.

Should the Chiefs not add a player from outside the building, it is reasonable to expect Steele to be Kansas City’s choice to replace Pacheco on early downs, with newcomer Samaje Perine working in as the third-down, pass-catching back.
