Spence (22-0, 19 KOs), of Dallas, traveled to England to dethrone IBF 147-pound champion and hometown favorite Kell Brook on May 27 on SHOWTIME in one of the defining fights of 2017.  The 27-year-old, who had long been touted as boxing's next big thing, fulfilled his promise with a breakthrough performance, fracturing Brook's orbital bone en route to an 11th round TKO. 

A 2012 U.S. Olympian, Spence will enter the ring at Barclays Center for the third time after most recently stopping former champion Chris Algieri in an April 2016 main event. He will fight in Brooklyn for the fourth time; he earned his title shot by knocking out Leonard Bundu at the Ford Amphitheater at Coney Island Boardwalk in August 2016. 

Peterson (35-3-1, 17 KOs), of Washington, D.C., has won titles at 140 and 147 pounds while facing some of the biggest names in the sport, including Danny Garcia, Amir Khan and Timothy Bradley. 

The 33-year-old won the WBA 147-pound title in his last outing Feb. 18 on SHOWTIME before relinquishing the belt for the chance to challenge Spence. Peterson has won four of his last five outings, twice fighting at Barclays Center. His Brooklyn debut saw him defeat Edgar Santana by TKO in 2014 before dropping a narrow majority draw to Garcia in a 2015 main event in Brooklyn.
