The Cleveland-Pittsburgh Monday Night Football matchup is off to a bizarre start. 

After the Steelers started the game with a pick-six just nine seconds into the first quarter, their kick returner, Gunner Olszewsky made a mind-boggling mistake on a kickoff after a Cleveland field goal.

While attempting to catch the ball close to the sidelines, Olszewsky tried to inexplicably toe-tap on the sideline instead of allowing the ball to go out of bounds. If Olszewsky would have chosen to let the ball go out of play, the Steelers would have been awarded the ball at the 40-yard-line.

Instead, his gaffe backed Pittsburgh up at their own 9-yard-line.

NFL fans absolutely roasted Olszewsky.
