World champion Lisa O'Rourke has been ruled out of the National Elite Boxing Championships.
The Roscommon fighter sustained a broken thumb in a sparring session. Following surgery, the thumb is now in a cast.
Her clash with Amy Broadhurst in the welterweight division was expected to be one of the highlights of the championships, which start this weekend.
Broadhurst [light welterweight] and O'Rourke [light middleweight] both claimed gold medals at last May's Worlds in Istanbul.
Broadhurst was shortlisted for the RTÉ Sportsperson of the Year, while O'Rourke was one of the nominees for the Young Sportsperson of the Year.
