Smith was placed on the reserve/COVID-19 list Friday, Gilbert Manzano of The Orange County Register reports.
Smith has been dealing with a core muscle injury recently that forced him to miss Saturday's preseason opener against the Rams, and he'll now have to spend some time away from the team due to the league's health and safety protocols. It's not yet clear whether the 2016 fourth-rounder has tested positive for COVID-19, but he'll likely miss Sunday's exhibition matchup against the 49ers.
