Nacua exited Tuesday's practice with minor groin soreness, Ian Rapoport of NFL Network reports.
The Rams are "just being cautious" with their star receiver, according to Rapoport, after he left the field with the training staff during Tuesday's joint practice with the Cowboys. It sounds like Nacua has avoided anything serious, and there's been no indication his availability for Week 1 of the regular season is in jeopardy.
