"After the Canelo loss you went on a losing streak – family, wife and then you go out and tweet to the heavyweight champion of the world. What is wrong with you, mate?" Khan responded by throwing his glass full of water towards Lo Greco. The bout was fought at a catchweight of 150pounds, as requested by Lo Greco's team. Khan trained with Joe Goosen for the fight, with Virgil Hunter unavailable due to ill health. The fight would be the first boxing main event to stream on ESPN's new streaming service ESPN+. Khan knocked Lo Greco out in 39 seconds of round one, setting a new record for himself. The first knockdown occurred after just 15 seconds when Khan landed a right hand to the head. Lo Greco appeared hurt, but managed to beat the 10 count. When the action resumed, Khan quickly moved on Lo Greco, putting him against the ropes with a flurry of punches until he dropped once more. Referee Victor Loughlin called a halt to the fight immediately. After the fight, rival Kell Brook, who was on pundit duty, entered the ring and the two boxers traded words. Khan said, "The weight is an issue with Kell, I'm a 147 lbs fighter. I will fight and beat Kell Brook and the world knows it."
