Steelers' Ryan Shazier misses practice with knee injury

Pittsburgh Steelers linebacker Ryan Shazier was added to the injury report and held out of practice Thursday with a knee issue.

There's yet to be an indication that Shazier's playing status for Sunday's game against the Seattle Seahawks is in doubt, but injuries arising mid-week are never a good sign.

The 2014 first-round pick's presence in the front seven would be crucial for Pittsburgh's chances of slowing down a Seahawks running game that's maintained its high level of production despite an injury to Marshawn Lynch.

Shazier tallied 47 tackles, three sacks, and two forced fumbles in just six starts.
