The Cowboys officially made quarterback Tony Romo inactive for Sunday’s game against the Cardinals, confirming the Sunday morning reports that Romo’s back injury would not allow him to play.

Romo wasn’t the only questionable player to wind up on the inactive list. Left guard Ronald Leary is also going to miss the game because of the groin injury that has bothered him all week.

With Leary and right tackle Doug Free both on the sideline, the Cowboys will be without two members of their starting offensive line. Jermey Parnell will start in Free’s place again this week and Mackenzy Bernadeau will replace Leary.

With no Romo and two missing offensive linemen, DeMarco Murray could be hard pressed to cross the 100-yard mark for the ninth time in nine tries this season. He’s unlikely to lose the league lead in rushing should that happen, but it could knock him off pace to break Eric Dickerson’s single-season rushing mark.
