Later tonight in Sheffield, former world champion Kell Brook will take part in his second fight of the year.

Brook will collide with top rated contender Michael Zerafa, who vowed to spoil the Sheffield boxer's homecoming.

The contest was expected to be Brook's final bout before a long awaited showdown with domestic rival and fellow former champion Amir Khan.

Khan was in action earlier this year when he knocked out Phil Lo Greco in 39 seconds in April.

But Khan had his share of troubles when he fought Samuel Vargas in September - as Khan was dropped in the second round and was also rocked in the tenth.

Things have taken a turn for Brook, as Khan is now instead considering the scenario of accepting a $5 million guarantee to face WBO welterweight champion Terence Crawford on March 23 at Madison Square Garden in New York City.

Brook has expressed his obvious anger in the media - calling Khan a "coward" and "Amir Con."

Khan believes Brook is physically close to done - after suffering back to back stoppage losses against Gennady Golovkin and Errol Spence. Brook sustained fractured orbital bones in both contests.

“I can't see that much left in him after having both his eye sockets broken and having his boxing broken,” said Khan to The Independent.

“He's living a bit of a crazy life. I don't know if he's doing it for the money or I don't know what he's doing it for. Maybe that's one of the reasons he's fighting all these easy opponents because he knows if he fights someone half decent, the fight with me might be off. The only option he's got out there is me, other than me he's got nobody else.

“I'm speaking the truth and speaking the truth is going to hurt him and I'm breaking him down. Skill wise, I can out-box him anyway, and out-beat him. He's not going to be nice, we're not friends, we've got to go in there and its business to us."
