This is the last sight any Cowboys fan wanted to see, in the preseason no less

What a disaster.

In the Dallas Cowboys third preseason game Thursday night, quarterback Tony Romo went down with what appeared to be a back injury.

After a fantastic block by rookie Ezekiel Elliott, Romo attempted to scramble for the first down and got folded up before exiting the game. Romo was just three plays into his second appearance of the preseason.

In 2013, Romo suffered a season-ending herniated disk. In 2014, he fractured his back.

It seems like Romo is fine for now, but the Cowboys are certainly lucky to have electric rookie Dak Prescott as a reserve. We'll continue to update Romo's status moving forward.

According to ESPN, Romo wanted to go back into the game, but the coaches made a decision to hold him out. He's unlikely to play again until the season-opener.
