Watch the Deontay Wilder-Artur Szpilka heavyweight title fight live right here on SI.com for the first time in boxing history.
This weekend marks the first time that a heavyweight title fight will be held in the Brooklyn borough of New York City in 115 years, going all the way back to when James J. Jefferies defended his title, one year into a six-year reign as the heavyweight champ. (Fun fact: Jefferies knocked out James J. Corbett in the 23rd round of a 25-round fight.)
In the main event at the Barclays Center, Deontay Wilder will be looking to increase his stature in the heavyweight division with his third title defense, against Polish contender Artur Szpilka. And for the first time ever in boxing history, as part of Showtime's Free Preview Weekend, the fight will be available for boxing fans to watch live, for free, right here on SI.com. To get yourself prepared for the big fight, check out SI.com's preview with everything you need to know about Wilder-Szpilka.
Tune in on Saturday at 10 p.m. EST to catch the first-ever heavyweight title fight available for free from Showtime via YouTube. And following the fight, check back in at SI.com/boxing for insights and analysis from senior editor Rich O'Brien.
