Nacua (groin) isn't practicing Monday, Sarah Barshop of ESPN.com reports.
Analysis:Nacua now is ticking toward two weeks off the practice field due to soreness in his psoas, but he was able to work with a member of the Rams' training staff on a side field Monday, indicating he's making some progress. In the end, the team likely is being as cautious as possible with Nacua with a Week 1 matchup with the 49ers in mind.
