Rather than pump the tires for their pay-per-view exhibition scheduled for November 28 in Los Angeles, Tyson had difficulty keeping his wits about him and at one point appeared to be asleep.
"I think it's very wonderful that we're fighting together", said a tired-looking Tyson, who was seen rubbing his head and moving slightly out of camera view on multiple occasions throughout.
"No problem, Champ", Morgan wrote in a reply. "I had no monitor so I couldn't see you guys and forgot to look into digicam". "Appreciate this message as some viewers were concerned".
