Depends on the size of the tear. If it's small they'll do anti-inflammatory mess and see if he can play with it.
If its a llarge one he can't play with it's surgery of which there is two types.
1. On the inside where they remove the torn piece and it's 3-8 weeks depending on how much needs to be removed.
2. If it's on the periphery it's a repair and it's 9 months give or take depending on the type of repair they use.

The Athletic trainer is NOT responsible for preventing the injuries. This is the responsibility of the strength and conditioning staff.
The Athletic trainer is responsible for treating injuries after they happen and returning them to their prior level of function.
Changing the head Athletic trainer will not change the occurrence of the injuries. It may change in how quickly they return.
