Brook looked proper cut earlier on the weigh in, fair play to him. The only thing for me, is it seems Brook wants the fight more than Khan. If Khan still has his speed, he wins, I doubt Brook will have the timing.
Brook always seemed the sort of guy you would not shy away from in a pub if he got a bit lairy, with his squeeky voice and Demeanour. Proves you can never judge anyone by looks alone, he would destroy many a geezer.
