It's all over. Gethin dropped twice in the seventh, the second time taking the full count while on his knee. The Briton attempted to return fire at times but Diaz was a different class, a left uppercut the final blast. The Panamanian was never in any trouble and Gethin seemed to realise the task was too tall early on in the contest.
Gethin down and in trouble. His nose looks broken, blood trickles down his chest. The gulf in class widens. Gethin doesn't look like he wants any more as he heads back to his corner. The belief draining from him as his corner urge him to continue. He looks like he wants to quit. The end must be close.
The fifth an intriuging three minutes. Gethin not allowing the smooth boxing of Diaz to take charge, but he looks the inferior fighter in there.
Diaz started the fourth well but the underdog gritted his teeth and rallied hard in the second half. The belief is growing in the Walsall man and he appears to take the round. The respect he has for Diaz seems to be subsiding.
Does Gethin believe in himself at this point? He's happy to motor forward but the quality is pouring in from Diaz. The visitor in charge and easing into the task ahead.
Diaz in control in the second session, his slick movement looking superior. But Gethin seems to be warming to the task.
The visitor takes the opening round with sharp boxing on the inside. Dean Powell urges Gethin to up his workrate before the second.
To Gethin, that introduction, that national anthem, will be every bit as intense as it was for Carl Froch in the O2 last week. This is a huge fight for him.
Anthony Crolla and Steve Lillis pick Martin Gethin to beat Ammeth Diaz. Should their prophecies come true, it will be an astonishing career turnaround for the Midlander. An IBF lightweight title shot awaits the winner.
