Coach Sean McVay said Nacua left Tuesday's joint practice with the Cowboys early and that he doesn't have an update on the wide receiver's status, Lindsey Thiry of ESPN.com reports.
Nacua exited with the Rams' training staff, indicating that he's dealing with some sort of health concern. The team doesn't seem to be treating the issue as a serious one, but it could still keep Nacua out of the lineup for Saturday's preseason game against Kansas City.
