Sheffield's Kell Brook is making his long-awaited return to the ring following nearly a year out. The unbeaten 29-year-old makes the third defence of his IBF World Welterweight title against the little known Canadian fighter Kevin Bizier at the Sheffield arena.
Kell Brook is nicknamed the Special One but he has had little chance to prove it of late. It has been 10 long months since he last stepped into the ring after a rib injury ruled him out of his last fight back in October.
His opponent tomorrow - Canadian Kevin Bizier - has lost only 2 of his 27 professional fights. But both those were at the hands of Jo Jo Dan. The man Kell beat within 4 rounds just a year ago. It's therefore no surprise Kell is the overwhelming favourite and has already started thinking about what could come next.
The big fight he craves could come as early as this summer, but first Kell must ensure he does the biz against Kevin Bizier.

Kell Brook has been forced out of his IBF World Welterweight title clash with Diego Chaves at the Sheffield Arena on Saturday October 24 after sustaining a rib injury in sparring.
Brook was set to make the third defence of his belt against the dangerous Argentine, but having spent time in hospital with the injury and taking the advice of medical experts following scans, the Sheffield star will now look to face Chaves later in the year.
The Sheffield show goes ahead with the Sky Sports debut of Chris Eubank Jr topping the bill as he defends his WBA Interim World Middleweight title against American Tony Jeter, Gavin McDonnell defends his European Bantamweight strap against former World title challenger Jeremy Parodi, along with a host of exciting young talent on the bill.
It's always a bitter blow when an injury causes a fight to be postponed, especially so close to the event. Kell picked up a rib injury in sparring yesterday and spent most of the day at hospital yesterday. Kell was desperate to fight but it was simply impossible and we will now look to reschedule the bout for the end of the year.
