Welterweight world titleholder Errol Spence Jr.’s first defense against former titlist Lamont Peterson now has a date and venue. The fight will take place on Jan. 20 (Showtime) at Barclays Center in Brooklyn, New York, multiple sources with knowledge of the plans told ESPN on Saturday night at the Deontay Wilder-Bermane Stiverne II fight at Barclays Center. The fight was announced two weeks ago for January but no date or site had been determined. Spence (22-0, 19 KOs) won the title on the road in May in Sheffield, England, where he knocked out Kell Brook in the 11th round. In February, Peterson (35-3-1, 17 KOs) won a secondary title by decision over David Avanesyan but vacated in order to finalize the fight with Spence.
