Shawn Porter to face Kell Brook after Paulie Malignaggi stoppage

Shawn Porter has successfully defended his IBF welterweight title with a fourth-round stoppage of Paulie Malignaggi.

The unbeaten American caused a surprise in December when he captured the world title off Devon Alexander, but the 26-year-old proved that the victory was no fluke by quickly dismantling Malignaggi in Washington.

The opening round was even, but at the start of the second, Porter took control with a series of hard-hitting punches that left Malignaggi struggling to make the bell.

The third was a repeat of the previous round, and in the following stanza, Porter dropped Malignaggi with a right hand, and although the Brooklyn fighter beat the count, he was soon on the canvas for a second, and final, time after being battered into submission by the champion.

Porter will now face British welterweight Kell Brook in a bout which is likely to take place in the United States in July.
