The four-fight main card will also include a bout between Shakur Stevenson and Christopher Diaz, a showdown between Teofimo Lopez and Edis Tatli, and a bout between Felix Verdejo and Bryan Vasquez. It’s a pretty stacked card and there are some good fights on the prelims as well. Crawford is 34-0 as a professional, with knockouts in his last three fights, the most recent being a TKO over José Benavidez Jr.He’s finished 25 of his 34 wins via knockout. He currently has the WBO welterweight belt, and previously vacated belts at light welterweight. His move-up fight was against Jeff Horn, which he won via TKO in June 2018. Khan wasn’t the first choice for Crawford’s next opponent, but it should be an entertaining scrap, regardless. He’s a former world champion and has a 33-4 professional record. He has 20 knockout victories, but three losses by knockout. His most recent loss was to Canelo Álvarez in May 2016, a knockout. He was out of the sport for a couple years, but has since beaten Phil Lo Greco and Samuel Vargas. Stevenson and Diaz will probably combine for the most intriguing bout on the main card. Stevenson is 10-0 as a professional and everyone is still unsure where his ceiling is. Diaz is 24-1. Lopez is also undefeated, at 12-0, and he faces the experienced and tough Edis Tatli, who sits at 31-2 for his career. Below is all you need to know to watch the action.
