Gable had about 25 seconds left in the match after Wyatt's TD, but was belly down on the mat. If MN threw the brick to challenge the takedown, they would of lost the challenge (of course) but Gable would've gotten a re-start from the referee's position, where he'd have a better chance of getting an escape.
So was MN out of bricks? Were they too ethical to abuse the rules this way? Or did they just not think of this?
