Pound for pound superstar Terence Crawford is in countdown mode to the biggest fight of his career.

The switch hitting supremo locks horns with Viktor Postol, live on BoxNation in a World Title unification showdown, which is arguably Crawford’s biggest test to date.

"On paper you could make a case that Postol will be the toughest man I have faced inside the ring, but I won't really know that until I fight him on July 23,” explained ‘Bud.’

Crawford has published various training videos across his social media channels to show the graft that’s been put in ahead of fight night.

“When I go into camp, I always assume the opponent I'm training for will be my toughest test. It's the only way I know how to train. I respect any fighter who laces up the gloves and enters the ring to battle with me. I take no opponent for granted and I take nothing in training camp for granted.”

The lure of picking up another World Title, the famous green and gold WBC strap and cementing his place at the top of the pile in the 140 lbs division is Crawford’s drive in this contest.

“Against Postol, I'm not just defending my belt, I'm out to take his too. That's the reason for taking such a tough fight. It is because I wanted to fight the best fighter out there. To beat the best fighter out there. To show that I am the best fighter in the division,” revealed the Omaha hero.
