Marcus Gilbert leaves Thursday Night game against Tennessee with right leg injury

The Steelers have lost both center Maurkice Pouncey and right tackle Marcus Gilbert in the first half of their game at Tennessee on Thursday Night Football.

It's flashes of the same thing the Steelers' offensive line has seen in this year, and in years past.

Injuries don't come single spice; they come in battalions.

Mike Adams has replaced Gilbert and Doug Legursky has replaced Pouncey.

The Steelers do not have another offensive lineman dressed. Oddly enough, for the third time this season, we've written we do not know who the emergency offensive lineman would be in the event of another injury, but our guess would be Heath Miller would replace a tackle, and they'd move the interior around if necessary.

The Steelers' defense has looked soft in the first half, and their offense is beginning to stall after a decent opening few possessions.

Tennessee holds a 13-10 lead in the first half. We'll have more updates as they are reported.
