The 2004 World Wrestling Entertainment (WWE) draft lottery took place at the Joe Louis Arena in Detroit, Michigan on March 22, 2004. The draft took place live for two hours on WWE's flagship television program, Raw on Spike TV. Post-draft trades were announced on WWE's official website, WWE.com, until midnight on March 22, 2004. There were twelve draft picks, with nineteen superstars overall switching between the promotion's two brands: Raw and SmackDown!. During the draft lottery, the General manager of Raw, Eric Bischoff, and the General manager of SmackDown!, Paul Heyman, stood on opposite ends of the stage on the Raw set, where they drafted six superstars randomly via two machines. At the conclusion of the draft, the two GMs would then be allowed to trade anyone on the roster until Midnight EST, which was later extended until Tuesday night after Heyman resigned. Every WWE employee was eligible to be drafted, including injured superstars, commentators, champions, and general managers.
The main event was a SmackDown exclusive match, in which Eddie Guerrero defeated Triple H to retain the WWE Championship by disqualification after Christian attacked Guerrero resulting in a brawl between SmackDown and Raw superstars.
