Yukio Kagayama will miss this weekend's fourth round of the MCE British Superbike Championship, due to his injuries sustained last month at Oulton Park.
The Japanese sustained a fractured T5 vertebra in his race one fall at Oulton. Doctors initially suggested several weeks' rest, but following a further private examination on Wednesday at London Bridge Hospital, Kagayama has been advised to delay his return to competitive action after it was decided that the fracture had not repaired sufficiently.
"It's disappointing, but the fracture was serious and despite the fact that Yukio feels well in himself now, we cannot risk any long term injury, especially by returning to such a physically demanding track like Cadwell Park,” said team manager Jack Valentine.
“With a bit more time to recover, Yukio should be back to full-fitness at Mallory next month. In the meantime, I can also confirm that we will not field a replacement rider this weekend, so Tommy will fly the flag at Cadwell for the Worx Crescent Suzuki Team alone."
Team-mate Tommy Hill is leading the BSB championship.
