Input: Kell Brook has vowed not to make the same mistake as the man from whom he ripped the world crown when he makes the first defence of his IBF welterweight title in Sheffield on Saturday night. Brook takes on Canada-based Romanian Jo Jo Dan in a bout which bears all the hallmarks of a triumphant homecoming before the 28-year-old sets his sights on much more lucrative 147lbs assignments. Brook had himself been considered a convenient underdog when he went to California in August and surprised the incumbent champion Shawn Porter to wrest the belt by split decision.
