McIntyre and the Irish legend challenged Intercontinental Champion Gunther at the SoFi Stadium in Hollywood.
The three heavyweights put together one of the greatest WrestleMania fights of all time that may have stolen the show.
Gunther picked up the win after Powerbombing Sheamus on McIntyre before repeating the same move on the Scotsman for the victory.
As the Austrian walked to the back with his belt to celebrate, the cameras went off in California.
Sheamus and McIntyre then broke character by hugging each other in the middle of the ring.
The two heavyweights also received a loud ovation from the crowd after an incredible display.
The former world champions entered the match as rivals and hinted that their friendship was on the brink of falling apart over the Intercontinental Championship.
That took place amid intense rumours suggesting McIntyre is on his way out of WWE.
The two-time world champion’s contract is in its final year and there are “no signs” of an extension after WrestleMania.

There has reportedly been no progress towards a new deal between the wrestling giants and the 37-year-old.
The exact reason why negotiations have hit a snag between the two parties is currently unknown.
That means this could have been the first ever British WWE Champion’s last ever WrestleMania.
