After leaving Japan, Goldberg signed a one-year contract with World Wrestling Entertainment (WWE) in March 2003, debuting on the March 31 episode of "Raw" (the night after WrestleMania XIX) and starting a feud with The Rock by performing a spear on him. Their rivalry intensified when The Rock held a segment entitled "The Rock Concert", where he taunted Goldberg along with Gillberg, but Goldberg defeated The Rock in his debut match at Backlash on April 27, following three spears and a "Jackhammer". Goldberg went undefeated over the subsequent half-year, defeating 3-Minute Warning in his first match on "Raw" on May 5. Goldberg defeated Christian the following week on "Raw" in a steel cage match. Goldberg next began a feud with Chris Jericho, culminating in a match between the two at Bad Blood on June 15, which Goldberg won.
