Lenny Daws sees his clash against Nigel Wright for the English light-welterweight as a crossroads fight for both men. In fact, Daws admits if he loses he'll have to consider retirement.
Daws, 29, from Sutton, faces a rematch on Wednesday against Crook's Wright - the man Daws beat to win the British title last year.
Speaking to his local paper, the Sutton Guardian, Daws said, "If I lost I would have to seriously think about whether I carry on.
"It is an important one for both of us because, if he loses to me again, everyone will be saying he is finished.
"I would not like to think what it would do to his career if he lost. If he can't get past me, it is a case of where does he go from there and it is a bit the same for me.
"I need to be winning all the time, otherwise I will start to slip down the rankings.
"People will start to lose interest and question whether I have got it in me to step up again.
"I feel as good now as when I won the British title except I have now got even more hunger to get back to the top.
"I need to win and look good so everyone knows I still mean business. This is as big as it gets for me."
