The calf injury Nacua sustained Thursday is believed to be "more minor than anything else" and "not significant," Ian Rapoport of NFL Network reports.
Nacua left Thursday's practice with the calf issue, and tests performed afterward appear to have indicated he did not sustain a serious injury. The report notes that Nacua's availability for Week 7 remains uncertain, but the Rams will presumably provide an official update on both his short- and long-term status at some point Friday.
