BBC Sport - Darleys Perez v Anthony Crolla: 'Perez a champion against the odds'

Perez's rocky road to world title

31-year-old Darleys Perez grew up in the midst of civil conflict in Colombia, but thanks to his boxing, he managed to steer clear of the paramilitary fighting which killed his brother.

Perez will fight Britain's Anthony Crolla on Saturday in order to defend his WBA lightweight title.
