Undefeated British and Commonwealth super-welterweight Champion Liam Williams has been ruled out of his title defence against Nav Mansouri.
Williams was scheduled to defend his titles in Liverpool on 13 February.
But the 23-year-old has been struck down with a viral infection and no new date has been announced for the fight
Williams claimed the vacant British light-middleweight title with a stunning second-round win over Kris Carslaw in December.
The Clydach Vale fighter was fighting for the first time in 13 months after recovering from two hand operations.
