When you have hurt yourself in a game, you need to take the time off to recover.
Many dedicated players like Manu Tuilagi would have still continued with the injury they sustained if given a chance. However that would only jeopardize their health and their future in professional rugby. For these reasons Manu Tuilagi was kept out of the tour of England with Australia. When Leicester suffered a defeat at the hands of Saracens in the semi finals of the Premiership, Manu was found to be limping out of the field. He was diagnosed with injury to the hamstring. As a result the Center ruled out his participation in the forthcoming tour.
