Late Sunday night, the Baltimore Ravens learned that multiple members of the organization, including running backs Mark Ingram and J.K. Dobbins, tested positive for COVID-19, team officials said in a statement.
Players are tested before each game but results are typically not available until hours after.
"We will continue to work closely with and follow guidance from the NFL, team doctors and our medical trainers," team officials said in a statement.
The Ravens face a short week. They are scheduled to travel to Pittsburgh for a Thursday night game against the Steelers.
The news leaves Gus Edwards and Justice Hill as the only running backs on the depth chart.
