When the dust settled at SummerSlam, it appeared that The Undertaker, who forced Brock Lesnar to pass out while locked in his signature Hell's Gate finisher, won the match fair and square. But upon further review, The Undertaker may have tapped out earlier in the fight, and SummerSlam ended with angry fans and a bit of controversy. 

The Undertaker got some help in order to gain his victory, as the timekeeper rang the bell when the ref didn't ask for it, which allowed The Undertaker to hit Lesnar with a low blow before putting him in Hell's Gate.

Fight over, right? Not so fast. Replays appear to show The Undertaker tapping out while he was caught in Lesnar's Kimura lock, as you can see in the GIF above. 

Regardless, this all seems point to a third, rubber match-style fight between the two sometime down the road. We can only hope it's a clean one.
