The Denver Post has no further details. Like hamstring injuries, groin ailments can linger and are highly susceptible to setbacks. We'd recommend to pick up Eric Decker, who's scored three of the Broncos' first five touchdowns on the season. Royal could return without a role on offense. Decker is a much better option, and Demaryius Thomas (Achilles, hand) could conceivably beat him back to the field. Royal can be dropped in all leagues.
