Cody Barbierri is the person that was slapped at catering this week at WWE TV, according to Wrestling Observer Radio.
It wasn’t just a slap to the face. It was more like the David Schultz slap (the Schultz video from 1985 is on YouTube). There are wrestlers that are sympathetic to Del Rio but in reality the company didn’t have a choice and had to fire him. If the company didn’t fire Del Rio then they open themselves to a lawsuit. As noted, TNA has shown interest in him. AAA will likely make a big play to get him.
Also as noted, Del Rio had made up his mind that he was leaving WWE when his contract expired.
