Terence Crawford has retained his title by a TKO at the 0:47 mark of round six.
It was ruled an accidental blow by referee David Fields and Khan would have been given five minutes to recover, but instead Khan’s corner informed the ref that he won’t be able to continue. Maybe he was looking for a way out the way things were headed.
The American is The Ring's number two ranked pound-for-pound boxer.
Meanwhile, this was Khan's first world title fight since a KO loss to Canelo Alvarez in 2016.
