Just when we thought things couldn't get more stressful for the Pittsburgh Steelers and their offensive line, another injury has popped up and set a new position battle into motion just a week from the start of the season.

First, we had rookie offensive tackle Troy Fautanu suffered a knee strain ending the position battle for starting left tackle for the time being.

However, when starting left guard Isaac Seumalo went down with a pectoral injury in practice, a whole new position battle arose. Seumalo's injury isn't expected to be season-ending however, he is sure to miss several weeks.

This means it will be a competition between veteran Spencer Anderson and rookie Mason McCormick for that spot in the starting lineup. McCormick has been impressive in the preseason but the Steelers might opt for the veteran experience of Anderson due to the fact that another rookie, Zach Frazier, is now the team's starting center.

Pittsburgh kicks off its season in Atlanta against the new-look Falcons. It is imperative the Steelers get off to a fast start this season to keep pace in a crowded AFC.
