You still haven't explained why Tommy should pay? He injured himself whilst training, he works for Manly Sea Eagles, therefore the employer is responsible for their employees safety & are responsible for injuries in the work place. It's not the point of how much he earns! He was injured at work, if the club wants him to participate this year then they can pay. It's why they pay for insurance policies. Imagine if Tommy was told he has to fork out the money.....he could say F Off & claim damages for loss of earnings for every year of his contract & sit at home.
Because the club has a responsibility to provide industry best practises in injury prevention, management and treatment ... this includes all medically recognised treatments.
The club is under no obligation to send a player overseas to undergo experimental, unproven treatments from a bloke who says he can cure hamstrings in 2 weeks .... it may choose to do so ... but it certainly has no obligation to do so.
