On This Date in WWE History: Brock Lesnar and John Cena collide for the WWE Championship

Don't adjust your calendars, Cagesiders, it isn't Sunday (April 29) quite yet.

That's when Brock Lesnar and John Cena will meet inside a WWE at Extreme Rules in Chicago, IL.

But nine years ago, almost to the day, the two went head to head for the WWE Championship at Backlash 2003. Spooky, am I right?

A villainous Cena -- if you can believe that -- challenged "The Next Big Thing" after Lesnar whipped the rappin' wrestler against the ring post with an F5, busting his knee up. Cena recovered and entered into a tournament to crown a number one contender following WrestleMania XiX.

He defeated the likes of Eddie Guerrero, The Undertaker and Chris Benoit to win the whole thing, earning a spot against Lesnar at the pay-per-view (PPV).

It's funny how as much as things change, they stay the same. While Cena is the Kangol-wearing, throwback jersey-sporting rapper he was then, his beef with Lesnar arises from a dastardly F5 from the big man.

Full match after the jump.
