Before waiving the flag to start NASCAR's Daytona 500, John Cena was interviewed for SPEED TV. During the interview, John mentioned how nervous he was about dropping the 45 pound flag and rooting for Carl Edwards. Cena then got a chance to hype this year's WrestleMania, where he takes on The Rock.

"April 1st, we have our Daytona 500," Cena explained. "It's going to be WrestleMania 28. I get to go one-on-one with 'The Great One.' I think it's going to be the biggest extravaganza that WWE's ever had."
