Apprentice James K. C. Chan picked up a chance ride in the opening event at Happy Valley last night - and ended up in hospital, writes Robin Parke. Chan came in for the ride on the grey Turf King when David Oughton's girl apprentice, Win Chung Lai-fong, cried off with 'flu. But Chan hit the Valley turf when Turf King clipped heels at the top of the straight and somersaulted spectacularly. Chan was taken to hospital with an injured shoulder but X-rays showed no breaks or a dislocation. The race also featured a sensational plunge on bottomweight Monopoly Senior (15-1 to 6.3-1) but the money was completely off target. Monopoly Senior finished last of the 11 who completed the course.
