Ngannou suffered memory and vision loss after the first round of his fight with Joshua

"When I was in the corner after the first round, my coaches were talking to me. And then my memory, vision and everything else was blown away. I don't remember getting up off the stool to go to the second round. It was so weird that way. So since I was in the stool between rounds, I wasn't there anymore. Sometimes it's just not your day," Ngannou said on his YouTube channel.

Recall, Joshua knocked out Ngannou in the second round, and in the first three minutes Francis was knocked out.
