The countdown is on for Kell Brook's huge title showdown against undefeated American Shawn Porter.
The Sheffield boxer will square of against Porter in an IBF welterweight world title clash in the early hours of Sunday morning. Brook becomes the latest in a long line of British boxers with the chance to come back from a big fight in the States as a world champion.
The fighter standing in the way of Brook is undefeated and the current holder of the IBF welterweight world title boosting a impressive (22-0-1) record.
Problems for Brook
Porter, who poses speed and power in abundance, powered through his last fights against Paulie Malignaggi and Devon Alexander and both were IBF title bouts.
Kell also poses an impressive record at (32-0) and like Porter is undefeated, with more fights under his belt.
Differences in fighter
However it is Porter who poses the big fight experience and the added advantage and experience of training with legendary trainer Freddie Roach.
But don't write Brook of just yet, as he has plenty to offer to. There is no doubt that Porter will be the best guy he's faced so far in his carer so the Brit must bring his A-game. Brook is also a powerful puncher and an entirely different opponent to the likes of Malignaggi and Alexander before him, who are seen as more slippery fighters.
He is more direct and can use both hands to devastating affect a fact his last four opponents know all to well.
All were defeated by TKO and he is fighter that poses deadly accuracy with acute timing that tends to leave his opponents on the canvas - Porter will have plenty to deal with come August the 17.
The build up
The lead up to this fight will have been immensely frustrating for Brook's camp, which missed out on three scheduled dates with former champion Alexander in 2013, due to injuries to both fighters.
When Brook was forced to pull out a second time, Porter duly stepped in to take the title from Alexander providing a powerful and decisive display along the way.
A gruelling regime that has made sure The Special One is ready both mentally and physically, ahead of what is arguably the biggest fight of his professional career against an equally big opponent.
And, after the disappointment of the last three fights that never came to be, Brook's camp made sure they waisted no time making sure the hard hitter from Sheffield was every bit as ready as he could be for his big moment in the boxing coliseum that is Las Vegas's MGM grand.
By the early hours of Sunday morning the boxing world will know whether or not the Match Room boxer really poses the talent to step up to the big stage.
One thing is for sure; a big performance from the aforementioned Special One will see doors open to the mega money fights he could have only dreamed of prior to his showdown with Porter.
