St George Illawarra forward Loko Pasifiki Tonga has been rushed to hospital in an ambulance following an incident at Thursday's training session.
The Dragons forward was seen on a stretcher being assisted by paramedics from the training ground at WIN Stadium.
The club is expected to provide an update on his condition imminently.
Rated one of the club's up-and-coming forwards, Pasifiki Tonga had been listed to play in Sunday's NSW Cup clash against Parramatta.
