Seth Rollins may have won but Shinsuke Nakamura had the last laugh in Pittsburgh.
The Visionary retained the World Heavyweight Championship in a highly physical contest against his rival, who had mentor and Hall of Famer the Great Muta watching at ringside.
Nakamura threw everything at the champion in a bid to take the gold, as he honed in on the legitimate back injuries which have been the focus of their rivalry in recent weeks.
However, Rollins was able to fight through the pain and managed to finally hit a Stomp to put the challenger down for a three count.
It was a triumphant end to the premium live event for the champ as he looks to move on and continue his run with the title, but it appears Nakamura has other plans in mind.
Although the show went off air for viewers at home with Rollins celebrating his win, there was some added drama only seen live by those in attendance.
In footage shared on social media, Nakamura can been seen attacking the champion from behind as he makes his way up the ramp, carrying on the onslaught until the pair were separated.
The Japanese star left to a chorus of boos, while Rollins was seen slowly getting to his feet after the unsporting beatdown.
It remains to be seen if WWE will be airing the attack as part of Monday Night Raw, given that it wasn’t part of the Payback broadcast for whatever reason.
Elsewhere on the show, Rhea Ripley and Rey Mysterio retained their respective titles, while Rhea’s Judgment Day allies to beat Kevin Owens and Sami Zayn to become tag champions.
