There is a big night of boxing in store tomorrow at the O2 Arena in London and headlining the event is Sheffield's world champion Kell Brook.
Brook is putting his title on the line against fellow Brit Frankie Gavin.
Words were exchanged between the pair at today's weigh-in ahead of the bill, which also features two more world title fights.

World Champion boxer Kell Brook has brightened up Sheffield this Bank Holiday by holding an open training session in the city centre.
The 29-year-old had his IBF belt with him and held it high in front of several hundred fans.
Sheffield boxer Kell Brook took part in the Sheffield half marathon at the weekend.
The welterweight world champion ran the 13.1 mile Yorkshire Half Marathon course for the Children's Hospital Charity and completed the course in one hour 35 minutes.
Kell Brook will defend his welterweight world title against Frankie Gavin in an all-British clash in London next month.
Brook, who defended his title against mandatory challenger Jo Jo Dan at the Sheffield Arena last month, will headline a pay-per-view show at the O2 Arena on May 30.
Gavin, 29, from Birmingham is the only English boxer to win a World Amateur Championship. However, he failed in his attempt to dethrone European welterweight champion Leonard Bundu last year.
Brook had been targeting a lucrative bout with Bolton's Amir Khan.
Sheffield boxer Kell Brook is on his way to London this morning where he will announce the name of his next opponent.
Amir Khan appears to have ended any hopes of a summer showdown with British rival Kell Brook after announcing his next opponent will be Chris Algieri.
Khan came under increasing pressure earlier this week to arrange a fight with IBF welterweight champion Brook, but the Bolton fighter instead looks set for an outing in Algieri's home city of New York on May 30.
While the non-title welterweight bout against Algieri has not been officially rubber-stamped, Khan is happy with his choice of foe.
Khan said: "You can class him as an A-class opponent."
Algieri's only defeat in a 21-fight professional career came last November, when he was knocked down six times en route to a heavily lopsided points defeat to Filipino superstar Manny Pacquiao.
Yet in his previous bout, the 31-year-old American upset the odds to win a split decision over the much-feared Ruslan Provodnikov and take the Russian's WBO light-welterweight title.
Khan, himself a former champion at 140lbs, added on his wife's YouTube channel:
"He has fought decent opponents, beaten decent opponents, and just fell short against Manny Pacquiao, which is an A star opponent.
"He's a decent boxer overall. He knows how to box and knows how to move well. He takes a decent amount of shots and he's got a decent amount of power, so I think overall it's going to be a good fight for me.
"Hopefully this can lead me on to the bigger fights in the future, which is what I'm looking at."
The 28-year-old has made no secret of his desire to fight the winner of the May 2 super-fight between Floyd Mayweather and Pacquiao, while he would also be keen on facing Brook in a "winner takes all" bout.
For now, though, Khan's focus is on his next opponent and he is keen to arrange the bout in New York.
Khan's only previous outing there was an 11th-round stoppage of Paulie Malignaggi at Madison Square Garden in May 2010.
This time, though, Khan wants the non-title bout at the Barclays Center as he said: "We're looking at fighting in New York, I think New York's a great venue for me.
"Having that fight in New York will be good for the UK fans in a way because it will give them a chance to travel and it won't be as far as going to (Las) Vegas.
"This time I'd like to fight at the Barclays Center, which I've never fought at."
Khan, who last fought in December last year with a one-sided points win over Devon Alexander in Las Vegas, hopes his next bout can be finalised soon.
"I'm looking forward to getting this fight announced officially by my manager and advisor Al Haymon."
"They think it's the right fight for me, they want to keep me going."
Kell Brook's trainer, Dominic Ingle, says that following his successful IBF Welterweight title defence, America has to start taking his fighter seriously:
Kell Brook, who successfully defended his IBF Welterweight title against Romanian Jo Jo Dan at the Sheffield Motorpoint arena says he had goosebumps walking out in front of his home crowd:
Sheffield's Kell Brook retained his IBF Welterweight title beating Romanian Jo Jo Dan by technical knockout in four rounds and remains undefeated.
Fighting at a packed out Sheffield's Motorpoint arena, the local fighter made the most the partisan crowd, starting on the front foot and continuing throughout.
Brook looked focused and composed as he took advantage of defensive mistakes by the mandatory challenger, and the bout looked settled from the second round, where Brook scored two knockdowns against the 33-year-old Dan.
It was truly amazing to walk out in front of all my fans and I didn't think I would ever box again.
A further two knockdowns in the fourth round, one of which came on the bell led to Dan's corner taking the decision to withdraw their fighter, keeping him on his stool before the fifth round could start.
It was Brook's first defence of the title he won from Shaun Porter since nearly losing his life when he was stabbed in the leg in Tenerife last September.
Brook's leg looked fully recovered and will now target Amir Khan, calling out the Bolton fighter. "If you're watching, come and get in this ring with me," Brook told Khan. Promoter Eddie Hearn added that Wembley Stadium was free for the pair on June 13.
Sheffield's Adam Etches lost his IBF Middleweight title to a fourth round knockout from Belorussian Sergey Khomitsky.
Fighting at Sheffield's Motorpoint arena on the undercard for Kell Brook and Jo Jo Dan, the 24-year-old local, etches struggled against the veteran Khomitsky, despite a partisan home crowd.
