Teofimo Lopez will make his first title defense as undisputed lightweight champion against George Kambosos Jr. on June 19 at Miami's loanDepot Park, Triller Fight Club announced Tuesday.
The card will be co-headlined by a women's super middleweight bout between Franchon Crews-Dezurn and Elin Cederroos, with all four world championship belts on the line.
Lopez (16-0, 12 KOs), 23, who became the undisputed champion last year by taking four belts from Vasiliy Lomachenko, is No. 5 in the ESPN pound-for-pound rankings.
He is No. 1 in the ESPN lightweight rankings, while Kambosos (19-0, 10 KOs), the mandatory IBF challenger from Australia, is ranked 10th.
Triller is a relative newcomer to the boxing promotion business. The tech company made headlines in November by promoting the exhibition between former champions Mike Tyson and Roy Jones Jr., and in February it won the right to promote the mandatory defense of Lopez, one of boxing's rising stars.
