"Right now there is some criticism of boxing, that the best aren't fighting the best. All you have to do is look at this card. These are the right fights. The right weight at the right time.

"June 25 we have two marquee matchups. All four fighters ranked in the top 10 in their respective divisions taking on each other. Thurman and Porter, Cuellar and Mares, this is the best doubleheader of the entire year. I will put these two fights against any doubleheader that airs on television. That was our focus when we turned to CBS for this broadcast.

"The Thurman v. Porter and Cuellar v. Mares fights showcase fighters in the primes of their careers. What we have here are four fighters that are willing to take on the best, not make a spectacle of it.  The go about their business with great care for the craft and they simply come to fight.

"Featherweight is one of the hottest divisions in the sport. You know Abner Mares, he has one of the best resumes in boxing. If you look at the list of fights that he has had, there aren't a lot of big names on it and now the New York City fans will get to see what he has to offer.

"The champion, Jesus Cuellar has quietly put together his own very strong resume. What we have here is a fascinating matchup."
