As the company's biggest star was doing an in-ring promo regarding his loss to Dwayne "The Rock" Johnson at Sunday's Wrestlemania 28, Lesnar came out to a thunderous ovation in front of the Miami crowd.
Dressed in a Lesnar cutoff t-shirt and windpants, he came down to the ring and offered his hand to Cena but gave him an "F-5", his finishing move. He didn't get on the microphone and reveled in the cheers as the show went off the air.
The rumors of Lesnar's return began in earnest as Sunday approached with Wrestling Observer founder Dave Meltzer reporting that MMA's biggest pay-per-view draw over the past few years was in Miami for the event under heavy security. Last week, Johnson was coy when asked if Lesnar could be a future opponent for him at the 2013 Wrestlemania which increased the buzz.
After eight pro bouts, Lesnar retired from MMA last December following a first round defeat to Alistair Overeem at UFC 141. According to Meltzer, UFC president Dana White had no issues with Lesnar returning and actually purchased the Wrestlemania pay-per-view to see his friend Johnson in action.
According to WWE, the Wrestlemania event in Miami did an $8.9 million gate and drew 78.363 in attendance.
