Carl Froch suggests Amir Khan should retire

IBF super-middleweight champion Carl Froch says he would retire if he was Amir Khan after Danny Garcia condemned the 25-year-old Bolton fighter to his second consecutive defeat in Las Vegas .

Froch believes the defeat is "very damaging" to Khan's career, describing it as "a write-off".

Khan was stopped in the fourth round by unbeaten American Danny Garcia, who claimed Khan's WBA light-welterweight belt and held on to his own WBC title.
