Errol Spence Jr. on Saturday took the welterweight title from Kell Brook via 11th-round knockout at Bramall Lane Football Ground in Brook’s native Sheffield, Yorkshire, England.

Spence, of Desoto, Texas, dropped Brook in the 10th round. Brook, with his left eye badly damaged, took a knee midway through the 11th and the fight was over.

Brook (36-2) was attempting to make the fourth successful defense of his belt. He was coming off a fifth-round TKO loss to middleweight champion Gennady Golovkin.

Spence (22-0, 19 KOs), a 2012 U.S. Olympian, was in his first world-title fight. He was up by one, three and five points at the time of the stoppage.
