Broncos HC Nathaniel Hackett told reporters Wednesday that S Justin Simmons will miss "some time" with a thigh injury he suffered in Monday night's opener. NFL Network's James Palmer reports that he's "hearing" Simmons will land on short-term IR. That would mean at least 4 missed games. Caden Sterns and P.J. Locke look like the fill-in candidates. Denver also added S Anthony Harris to the practice squad Wednesday.
