Cena, who was advertised to work the final WWE live event before Sunday's SummerSlam pay-per-view, did not appear at the show in Portland, Oregon on Saturday night.
The reason Cena did not wrestle as advertised on Saturday night was because WWE has pulled him from all in-ring activity leading into Sunday's pay-per-view, due to the injury he sustained to his left elbow. Cena will, however, still compete on Sunday against Daniel Bryan in the main event of SummerSlam.
For whatever reason, WWE continued to advertise Cena on the day of the show in Portland on Saturday. Instead of the original main event, which was supposed to feature Cena, WWE put on an unadvertised Battle Royal, which Daniel Bryan won, earning him a shot at Alberto Del Rio's World Heavyweight Championship in the main event. Bryan won the match via disqualification, so Del Rio walked out of Portland as the champion.
We will have a full report from the WWE live event in Portland up on the website shortly.
