The Big Dog was denied the opportunity to make a SummerSlam challenge when a pile of scaffold and metal suddenly fell down upon him.

In the final moments of this week’s SmackDown LIVE, Roman Reigns was intending to make a SummerSlam challenge from the backstage area, but The Big Dog just barely evaded sheer catastrophe when tons of steel beams came plummeting toward him.

A preliminary investigation has found the incident Tuesday night involving Roman Reigns was caused by a forklift backstage carrying lighting grids that were not properly secured.
