Look back at this unseen footage of #leosantacruz pro debut. He knocked out Pedro Silva on October 13, 2006. Next Up for Top Rank Boxing, WBC/WBO/IBF light heavyweight king Artur Beterbiev now has a date to defend his crown. After recent dental surgery forced Beterbiev to postpone his Aug. 19 title defense against former world champion Callum Smith, the two will now meet Saturday, Jan. 13 at Videotron Centre in Quebec City, Canada. Beterbiev vs Smith and the co-feature will be televised live on ESPN. Undercard action will stream exclusively in the U.S. on ESPN+.
