Steelers TE Green misses practice, questionable for Dolphins (Yahoo Sports)

Pittsburgh Steelers tight end Ladarius Green sat out practice on Friday, putting his availability for Sunday's playoff game against Miami in doubt. Coach Mike Tomlin held Green out of practice after expressing concern about Green's performance in practice on Thursday. Green missed Pittsburgh's final two regular season games after being put in the concussion protocol following a helmet-to-helmet hit against Cincinnati on Dec. 18.
