Floyd Mayweather and Robert Guerrero have weighed in for their showdown for Mayweather's World Boxing Council welterweight world title.
Mayweather, returning to the ring after a year's absence that included two months in jail, weighed in at 66.2kg while Guerrero weighed in on the limit of 66.7kg.
Mayweather went to jail last June for domestic violence.
Since his release eight months ago he has been working to regain the fitness needed to defend his place atop the list of boxing's moneymakers.
Fellow American Guerrero, 31-1 with 18 knockouts and a 15-fight win streak dating back to 2005, says he'll hand Mayweather the first defeat of his career.
