The NFL has officially hit December as playoff races are heating up around the league. In what was one of the wildest weeks in recent memory, 12 games were decided by seven-or-fewer points -- tied for the most in a single week in NFL history.

The Baltimore Ravens released their Week 13 inactives and Marcus Williams and Keaton Mitchell are both healthy scratches against the Philadelphia Eagles
