The highly anticipated world title fight between Teofimo Lopez and Shakur Stevenson was marred by an ugly build-up at the news conference. The American fighters, both 28 years old, were set to battle it out at Madison Square Garden on Saturday for the WBO light-welterweight belt. However, tensions flared when Stevenson misheard a comment by Lopez as being about his mother, leading to a shouting match. Stevenson vowed to 'smack' his opponent, but later insisted the rivalry would be settled in the ring. The two-weight titleholder Lopez has won six fights in a row since his sole defeat in 23 outings to George Kambosos Jr in 2021. Stevenson, a three-weight world champion, has won all 24 of his professional bouts. The shouting match continued as Stevenson and his camp accused Lopez's father and coach of being too hungover to attend. Stevenson suggested without evidence that Lopez Sr had been drinking at a hotel the previous night. Lopez later struck a calmer tone, saying, 'My soul is a beacon. We have something to cherish being here. We've got life. It's not about trying to be a thug in the streets.' The face-off ended with Stevenson delivering a light shoulder barge and walking off stage. But here's where it gets controversial... Will the fight live up to the hype? And this is the part most people miss... How will the fighters' personal histories influence the outcome?
