Lee Purdy is ready to make his mark in the welterweight division ahead of his world title bout with Devon Alexander in Atlantic City's infamous Boardwalk Hall on Saturday.

Purdy is being given next to no chance against the IBF's 147lb champion having come in as a late replacement for Matchroom Promotions stablemate Kell Brook, who had to postpone a long-awaited clash with the American for a third time after suffering a foot injury in training last month.

While Colchester fighter Purdy is ranked fourth in the IBF rankings, he has a rather modest record of 20 victories, three losses and one draw as well as barely any amateur pedigree.
