"This is a great opportunity to show the world I'm the best champion at 140,” said Crawford. “July 23 is going to be a great night of boxing. It’s number one against number two in a unification fight. On paper everyone says it&rsquo;s a 50-50 fight but in my eyes I’m going in there looking to destroy this man. I’m looking forward to putting on a great performance. After July 23 my record will be 29 wins with 21 knockouts!" he said.

"I have been waiting for this fight for a long time and I want to thank my promoters Elite Boxing and Top Rank for making this fight a reality for the fans. With the help of my team I will be ready come July 23 - may the best man win," said Postol.
