option 1:

The league is able to use the best in medicine and training to create an environment that rarely if every results in injury. Everyone in the league has their own trainer and team of doctors. Due to top secret FDA unauthorized techniques the SHL league players are able to stay in shape. The limited injuries that do occur are minor enough to be played through and any really bad injuries are healed up quickly thanks to the locker room doctors and the SHL patented healing bench technology. All of this tech is possible due to the fact the SHL is a simulation that blurs real life and virtual reality. The league is called Simulation Hockey League after all. Is real life even real? What is the meaning of life? We may or not be a punch of DND role playing hockey nerds........... 

This is not often talked about....... in fact....... I do not know what I am actually saying right now - gotta blast!
