It's been almost a year since his last fight, but Vasiliy Lomachenko is finally returning to the ring as he looks to claim lightweight glory once more.
Standing in his way is the unbeaten 26-year-old prospect Jamaine Ortiz, who has world title aspirations of his own.
This is by far Ortiz's biggest fight to date against one of the best talents to ever put on boxing gloves, but the American will be full of confidence after beating former super featherweight world champion Jemel Herring in May.

As previously mentioned, Jamaine Ortiz's biggest win of his career so far came this past May when he beat former super featherweight world champion Jemel Herring by unaminous decision.
Herring got off to a good start, he managed to establish his jab and in round three began to target Ortiz's head. However, the momentum swung in the fourth when Ortiz landed a left hook which buzzed Herring.
This shot had a lasting effect on Herring, whose punch output significantly decreased as the fight progressed, while Ortiz throughout the second half of the fight increased the pressure and made Herring look a shadow of his former self.
Following the 10th and final round, Ortiz was awarded the victory by the three ringside judges, who scored the fight 97-93, 96-94 and 97-93, which was then followed by Herring announcing his retirement from the sport.
The main card is set to get underway at 8 p.m. ET / 1 a.m. BST with the main event ringwalks scheduled for 10 p.m. ET in the U.S., and 3 a.m. GMT in the UK due to the clocks going back by one hour. These timings could change due to the length of the undercard fights.
