The NFL canceled practice for the Baltimore Ravens on Monday, one day before they're scheduled to play the Pittsburgh Steelers.

Baltimore has officially placed 18 players on the reserve/COVID-19 list in the past week and has since had three starters test positive.

As of Monday morning, the Ravens are still deciding on when to travel to Pittsburgh.

The outbreak in Baltimore already has caused the Week 12 game between the Ravens and Steelers to be postponed twice.
