Breaking News: Ben Roethlisberger Will Not Play Vs. Ravens Due To Concussion

In the disappointing loss to the Kansas City Chiefs last Sunday, Pittsburgh held their breath when quarterback Ben Roethlisberger went down with a "concussion-like injury."

The entire Steelers staff, lead by head coach Mike Tomlin, wanted to observe Roethlisberger's progress, and would make a decision as to whether or not No. 7 would play.

Earlier this week, Roethlisberger was rumored to start against the Baltimore Ravens, their division rivals, on Sunday.

Many tests were taken throughout the week, making sure Roethlisberger could hold his own in a match up like this.

As of Friday, he was determined a game-time decision. But that did not last long, according to Fox Sports .

According to FOX.com, Roethlisberger will not play against their rival Sunday, in what could be the biggest game of the year.

Both the Steelers and Ravens are fighting for playoff spots, and with the blow already to Troy Polamalu, they are taking it safe by resting their quarterback this week.

Due to Charlie Batch requiring season-ending surgery earlier this week, former Oregon quarterback Dennis Dixon will make his first career start.

The Baltimore Ravens and the Pittsburgh Steelers will square off in one of the NFL's more heated rivalries Sunday Night.
