Vasiliy Lomachenko, the WBO and WBA world lightweight champion and ESPN’s No. 1 pound-for-pound fighter, faces England’s Luke Campbell in the main event of a Top Rank on ESPN+ card at the The O2 Arena in London, England, on Saturday at 4 p.m. ET. Lomachenko, of Ukraine but living in Oxnard, California, will be looking to add the vacant WBC belt to his collection while Campbell, a big underdog, will aim to pull a big upset. Undercard fights will stream on ESPN+ starting at 1 p.m. ET.

Lomachenko (13-1, 10 KOs) has won nine of his last 10 fights by stoppage, including a fourth-round KO victory over Anthony Crolla in April at the Staples Center in Los Angeles.

Lomachenko, 31, a southpaw who underwent right shoulder surgery in May 2018, has won two consecutive fights since then.

This will be Lomachenko’s second professional fight outside of the U.S. In 2014, he traveled to the Cotai Arena inside the Venetian Resort and Casino in Macau and won a unanimous decision over Suriya Tatakhun to retain a featherweight world title.

Campbell (20-2, 16 KOs) has won three fights in a row — two by TKO — since suffering a split-decision loss challenging Jorge Linares for his WBA lightweight world title in September 2017 at the Forum in Inglewood, California. Campbell’s streak includes a fifth-round TKO win over Adrian Yung in the Tevin Farmer-Jono Carroll undercard in March.

Campbell, 31, of Hull in the United Kingdom, has a 2-inch height advantage and a 5 ½-inch reach advantage over Lomachenko, according to BoxRec. However, he’s a big underdog for Saturday’s fight (Lomachenko -2000, Campbell +1000).
