Vasiliy Lomachenko and Teofimo Lopez have met their required 14-day pre-weight checks ahead of their unification blockbuster on October 17.
Lomachenko tipped the scales at 141.4-pounds while Lopez came in at 142.4-pounds. Both men must make the 135-pound lightweight limit 24 hours before they clash to contend for the WBA Super, IBF and WBO titles at the MGM Grand Bubble in Las Vegas.
ESPN debuted the first of a two-part, behind-the-scenes look at the respective camps. The show provides boxing fans a peek behind the curtain of both fighters' regimens in Southern California and New Jersey.
Pound for Pound superstar Lomachenko is the quickest three-division world champion in the history of the male's version while Lopez is regarded as one of the brightest young fighters in the sport.
The latter has been the more vocal of the two going into the biggest fight of the year. Lopez - from Brooklyn - has told fans if they want to make some money then they should place a wager on him delivering a shock upset win.
"I want the odds to be more in his favor. That way, I can bet on myself and make some more money on the side. You know what I mean?
"But, you know, I think by the end of the night, once we get into after the weigh-ins and everything, I think this fight might end up becoming 50-50. You know what I mean? So, if you wanna make some money off of Teofimo, place your bets now."
Lopez added: "Really, it's just I'm gonna talk my talk and I'm gonna walk the walk. You know what I mean? I'm gonna talk my sh*t, and that's just who I am. You know, I know what I'm capable of doing. And at the end of it all, it's in my hands anyway. You know what I mean? When I'm in that ring, that's how I feel."
