There are two possible systems for player injuries in Strat-O-Matic Baseball 365. For the vast majority of leagues, the Standard Injury System is in effect, but starting with the 2015 Season set, a new, optional Super-Advanced Injury System was introduced, which is in effect for 2015 Season leagues explicitly created with the option turned on.
All Strat-O-Matic Baseball 365 leagues use the Standard Injury System, with the exception of 2015 Season, 2016 Season, and 2017 Baseball Daily leagues who have explicitly chosen to play with the new Super-Advanced Injury System.
Super-Advanced Injury System (optional)
The Super-Advanced Injury System is an optional system that's currently available for the 2015 Season, 2016 Season, and 2017 Baseball Daily sets only. It must explicitly be turned on for a league when it is created; otherwise the Standard Injury System above is in effect.
