Englishman George Groves has pulled out of his world super-middleweight title fight with Robert Stieglitz through injury.
The British and Commonwealth champion had planned to face the WBO belt holder in Germany on May 5.
"I am sorry to have to announce that I won't be boxing on May 5," said Groves.
"I have picked up an injury in the build up to this fight. We tried to work through it but soon realised I wouldn't be able to perform the training needed to prepare for this fight."
This is the second time this year that Groves has withdrawn from a fight. Last month a back injury forced the postponement of his bout with Kenny Anderson at Wembley Arena.
