For the second postseason game in a row, the Steelers will be without the keystone of their offensive line in center Maurkice Pouncey, according to this tweet by Gerry Dulac.

Maurkice Pouncey will not play in Sunday’s playoff game in Denver. Second postseason game in a row he will miss because of left ankle.

SB Nation confirms that Pouncey will be out, and has some ideas about how the Steelers will work to replace him.

Pouncey missed two of the Steelers final three games with the injury. His status for the game had been question but the Pittsburgh Post-Gazette reports he will not play. Doug Legursky will likely move from guard to center and Trai Essex will enter at guard.

We'll have more on this injury and what it means for the Steelers throughout the Playoffs at SB Naiton Pittsburgh, but for more on the Steelers, visit Behind The Steel Curtain.
