“As p***ed off as I am, it is what it is.
“I had a sharp, fast opponent and there were a lot of mistakes from me. Credit to my opponent and his team.
“We rolled the dice and came up short. You know I’m p***ed but I’m going to keep cool and give respect to my opponent.”

“It was a phenomenal fight, like Hagler v Hearns.
“A brilliant fight and everybody has seen a champion’s performance tonight.
“Daniel has shown his courage, his skills.
“AJ caught him with a shot towards the end and I was worried, but what a fabulous, fantastic fight.”
EDDIE HEARN (AJ'S PROMOTER)
“AJ shipped a huge right hand in the first round and was fighting on heart.
“He hurt Daniel at the end of the fourth and then again in the fifth, but got greedy and walked on to a right hand and that’s all she wrote.
“I’m sure Anthony will exercise the rematch clause.”
