Miami's Tannehill ruled out against Steelers; Moore to start (Yahoo Sports)

Miami Dolphins quarterback Ryan Tannehill has been ruled out of Sunday's playoff game at Pittsburgh, and backup Matt Moore will start for the fourth week in a row. The Dolphins determined Tannehill isn't ready to return from a sprained left knee he suffered in Week 14. Moore, a 10th-year pro, is 2-1 as Tannehill's replacement and will make his first career postseason start.
