The Ravens issued a statement announcing that Tuesday's team activities will be held virtually and their media session has been canceled:
Adam Schefter of ESPN reported the Ravens have had five players and four staffers test positive, adding that "further positives" could mean a postponement of their game Thursday night against the Pittsburgh Steelers.
Head coach John Harbaugh told reporters Monday that running backs Mark Ingram II and J.K. Dobbins tested positive for COVID-19. He also said team facilities were open again after contact tracing was conducted.
Because Ingram and Dobbins tested positive, both players will be unavailable against the Steelers.
Defensive tackle Brandon Williams will also be unavailable after being placed on the reserve/COVID-19 list Monday, though it wasn't specified if he tested positive or was a close contact of someone who did.
Per ESPN's Kevin Seifert, anyone identified as a high-risk close contact of someone who tested positive is required to undergo a five-day isolation period.
The Ravens previously placed seven players on the reserve/COVID-19 list Nov. 3, but six of them were activated prior to that week's game against the Indianapolis Colts. The seventh, Marlon Humphrey, was activated Nov. 11.
