5 biggest defeats of Brock Lesnar in the WWE

#2 John Cena (Extreme Rules 2012)

Cena had to rebound from the loss to the Rock at Wrestlemania 28

Nobody saw this coming – Lesnar’s first match in the company for eight years actually ended in defeat. Lesnar faced John Cena at the Extreme Rules PPV in 2012

Lesnar was dominant throughout the match until Cena punched Lesnar in the face with a steel chain wrapped around his fist. Cena then delivered the Attitude Adjustment to Lesnar onto steel steps and Lesnar lost the match.

Not a great way to begin your second run in the company.
