During a trackwork session at Mooney Valley, racehorse Via Sistina threw jockey James McDonald and ran riderless, but both were unharmed, leading trainer Chris Waller to await further vet assessments before deciding on the horse's participation in the Cox Plate. Meanwhile, jockey Jason Collett was lauded for his bravery after tending to his horse, Think About It, which collapsed due to a pulmonary hemorrhage during the Sydney Stakes. Despite fears of a grave injury, Think About It recovered and was retired from racing, with Collett's actions praised for demonstrating compassion and quick thinking amidst a dangerous situation. Both incidents highlight the unpredictable and hazardous nature of horse racing, as well as the dedication and care shown by jockeys towards their horses.
