Champion jockey Opie Bosson has been forced out of New Zealand Cup week, which begins at Riccarton on Saturday.
Bosson, who sits second on the New Zealand Jockey Premiership, received a head knock at the Avondale races on Thursday and failed a concussion test on Friday.
That means he facesa 12-day stand down from riding so is likely to miss the entire Cup week carnival: Saturday, Wednesday and next Saturday.
Bosson was engaged to ride second favourite Belle Cheval in the NZ 1000 Guineas as well as favourite Captured By Love in the $120,000 Windsor Park Breeders Stakes.
