Paul was confronted in the ring by Sami Zayn and the 27-year-old then delivered a questionable right hand which floored the honorary member of The Bloodline.
The YouTuber signed with the WWE back in June and has made frequent appearances on various shows ever since.

It has led to one of the biggest storylines in the wrestling world and there is belief that the fight will be announced officially soon.
The WWE has announced a press conference for Saturday in Las Vegas with rumours circulating that Reigns and Paul will be there to announce it.
But last night, Paul was one of the stars of the SmackDown show.
Video: Logan Paul punches Sami Zayn
Zayn walked towards Paul in the ring in an attempt to lecture the former opponent of KSI.
The Canadian Zayn said: “Look, you’re not from our world so let me just explain to you how things work around here.”
Before he could explain, Paul delivered a punch to the wrestler and it sent him straight to the canvas, but fans weren’t so convinced about the blow.
“What was that punch? Lol”, “So confused… Who throws a friggen punch/jab/whatever… without even moving their hips?” and “Oof. That jab was like modern Shane McMahon bad” were just three responses to the clip WWE posted.
“That was such a bad wrestling punch holy s***” and “What kind of punch was that? Kudos to Sami for selling the f*** out of it though” were two further replies.
The Ohio-born Paul then stood over the 38-year-old and the audience could be heard booing.
He then said: “How do the things work around here Sami? I’d like to know.”
The Usos and Solo Sikoa then ran into the ring, with Paul quickly retreating as the trio came towards him.
