Montgomery is one of three running backs on Houston's 53-man roster, along with Woody Marks and British Brooks, Jared Koch of SI.com reports.
Montgomery is ticketed for a prominent role after coming over from Detroit in an offseason trade, but it remains to be seen just how much Marks cuts into Montgomery's usage. The 230-pound Montgomery is much better-suited for running inside and short-yardage work than the 208-pound Marks, but Montgomery recorded only 76 receptions across the past three regular seasons in Detroit, so the shifty Marks could siphon away opportunities in passing situations.
