Nacua (groin) isn't practicing Monday, Sarah Barshop of ESPN.com reports.
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.
