England`s Kell Brook, who returned from an horrific knife attack last year, on Saturday retained his IBF world welterweight title.
The unbeaten 28-year-old floored Romanian challenger Jo Jo Dan four times in a four-round stoppage win six months after being stabbed with a machete in Tenerife.
Brook won the IBF title by beating America`s Shawn Porter last August, and he defended the belt against Canada-based Dan at the Motorpoint Arena in his hometown of Sheffield.
Soon after beating Porter, Brook sustained serious leg injuries in the machete attack while on holiday on the Spanish island of Tenerife, but declared last January he was ready to return to the ring.
He produced a dominant performance as he floored Dan twice in the second round. He was knocked down twice in the fourth and did not come out for round five.
Brook has a new record of 34-0 (23KOs).
Southpaw Dan entered the ring a heavy underdog with a record of 34-3 with 18 early wins.
Victory paves the way for a more lucrative fight this summer, with Brook targeting the likes of Juan Manuel Marquez, Marcos Maidana and, of course, fellow Briton Amir Khan.
