MGM Grand Conference Center, Las Vegas - WBO welterweight champion Terence Crawford (37-0, 28 KOs) made a statement as he overcame a slow start and then wiped out former IBF titleholder Kell Brook (39-3, 27 KOs) in the fourth round.

A very slow start by both boxers in the first round. The two eventually started throwing a few jabs. The fight continued at a very calculated pace in the second round. Both fighters was landing punches in a chess match, making the fight close.

Crawford was doing better in the third with the southpaw stance. In the fourth, a big right hand dropped Brook as he was stumbling backwards with ropes holding him up. Once the action restarted, Crawford began to batter Brook with punches and the fight was waved off.
