On the "SmackDown!" after WrestleMania, SmackDown! General Manager Stephanie McMahon announced Kurt Angle suffered a pulled hamstring and a neck injury, while Lesnar suffered multiple concussions. She later announced that a tournament would take place to determine the number one contender to Lesnar's WWE Championship. On the April 17 episode of "SmackDown!", John Cena would become the number one contender after he defeated Chris Benoit in the tournament's final match. At Backlash, Lesnar defeated Cena to retain the WWE Championship. Lesnar would then feud with Big Show, as he defeated him at Judgment Day to retain the WWE Championship in a stretcher match. Lesnar would however lose the WWE Championship to Angle at Vengeance in a triple threat match that also involved Big Show. Lesnar then regained the WWE Championship from Angle on the September 18 episode of "SmackDown!", in an Iron Man match winning 5-4.
