The Dolphins face the Steelers in Pittsburgh on Monday to close out Week 15. We break down what the game means for the NFL playoff picture.

On the NFC side, Green Bay Packers trade acquisition Micah Parsons suffered what is feared to be a torn ACL in Sunday's 34-26 loss to the Denver Broncos. Parsons has totaled 12.5 sacks, 12 tackles for loss and a forced fumble in his first season with the Packers.

The Dolphins are on a four-game winning streak, allowing only 13.3 points per game in that stretch, a significant turnaround after a 1-6 start to the season. A victory would bring them back to a .500 winning percentage. The cold Pittsburgh weather could be a factor for the warm-weather team.

The Pittsburgh Steelers' up-and-down year has raised questions about head coach Mike Tomlin's job security, and details about his contract have been revealed.
