The Rock reveals exactly what would happen if he fought Tom Aspinall in the UFC as knockout claim made

The Rock has revealed exactly what would happen if he fought UFC heavyweight champion Tom Aspinall inside the famed Octagon.

The Rock - real name Dwayne Johnson - will portray MMA legend Mark Kerr in his next big-budget movie project.

The Smashing Machine is a biographical sports drama that tells the fascinating story of Kerr, who was inducted into the UFC Hall of Fame on Thursday.

Johnson did the honours as he inducted Kerr into the UFC Hall of Fame at a ceremony in Las Vegas.

He paid tribute to the former UFC two-time tournament winner during his speech.

"It was important to pay tribute to Mark because of the life he lived," he said of Kerr. "MMA moves fast, and it’s an accelerated sport. Everyone is getting better and better every day, and we found that out making this movie, so what an opportunity for us to acknowledge Mark and the road that he paved for others."

Johnson also spoke about his love for MMA and thought about what it'd be like to be a UFC fighter.

In doing so, he name-dropped Aspinall, who was elevated to the undisputed UFC heavyweight champion following Jon Jones' retirement, and revealed how a fight with the British star would go down.

He hilariously claimed he would be knocked out in eight seconds by Aspinall.

"I love the sport of MMA as you guys know the respect I have," said Johnson.

"Coming out here and hearing my theme song I think 'sh*t, imagine if I was an MMA fighter'. Like a UFC heavyweight coming out to my music, my theme song, right? That’s cool."

The WWE legend added: "Man, well I don’t know about that but I’d give it a shot - headline would read 'Tom Aspinall knocks out The Rock in eight seconds'."

Johnson doesn't have to worry about fighting Aspinall and, who knows, maybe he portrays the new UFC heavyweight king down the road.
