The 49ers placed Helm on the practice squad COVID-19 list Friday, Matt Maiocco of NBC Sports Bay Area reports.

Helm has either tested positive for the virus or come into close contact with an infected person. He'll be required to clear the league's COVID-19 protocols before returning to team activities. The 49ers are in the midst of a bye week, and Helm is a candidate to be promoted from the practice squad as long as he's healthy.
