Injury forces champion Huck out of Larghetti bout
German WBO boxing champion Marco Huck reacts after his victory over German challenger Firat Arslan on January 25, 2014 in Stuttgart - by Sebastian Kahnert
Huck, who had been aiming to defend his title for a record 13th time, picked up the injury in sparring.
His injury is the latest in a series of unfortunate events that has led to the bout being cancelled.
The WBO Champion was a late addition, having stepped in for IBF cruiserweight champion Yoan Pablo Hernandez, who had originally topped the bill but withdrew with a viral infection.
