Amir Khan is three days away from the biggest test of his chin

By Bennie

Amir Khan is three days away from the biggest test of his chin since it failed alarmingly against a wild Colombian by the name of Breidis Prescott in September 2008.
It looked all over for the Bolton youngster, smashed inside a minute, but Khan was brought back with remarkable speed as he busted up Mexican great Marco Antonio Barrera, linked up with trainer Freddie Roach in the States, moved up a weight and won the WBA light-welterweight title, then retained against two non-punchers.
Now comes Marcos Maidana, a big-hitting challenger from Argentina who brings a 29-1 (27) record to Las Vegas on Saturday night for his long-awaited showdown with Khan. Maidana, 27, earned his chance 18 months ago with a thrilling six-round stoppage of the much-touted Victor Ortiz in Los Angeles, climbing off the floor three times to outlast and outgame Ortiz, since when he has fought and won three times.
He could not be avoided forever. The 24-year-old Khan has definitely improved since Prescott and he goes in as the betting favourite - but what happens when Maidana tags him on the chin?
