Porter emerged as one of the sport's hottest young fighters last December when he captured the IBF welterweight title from Devon Alexander by unanimous decision. He followed up with a Round 4 TKO over veteran Paulie Malignaggi in April.
At 26, Porter has followed a solid path of development as a professional. He served a stint as a sparring partner for superstar Manny Pacquiao. After drawing with the far more experienced Diaz in December 2012, he made adjustments and won decisively in the rematch.
Brook's career trajectory shares some similarities. He also struggled with a more experienced opponent in 2012, barely edging Carson Jones by majority decision. But, like Porter, he came out stronger in the rematch, winning by TKO.
Brook's quality of competition has lagged behind Porter's, but his Round 4 TKO of former titleholder Vyacheslav Senchenko was impressive.
These are two of the top emerging fighters in the welterweight division. It's always a treat when young stars like this face off.
