History

Historical Context

In 2009 MLB introduced its first formal concussion protocol, drafted by Dr. Robert Cantu and the MLB Players Association, requiring a 48-hour evaluation for suspected head injuries. The move followed earlier league-wide safety reforms, such as the 2004 drug-testing policy and the 2008 rule that suspended unfinished postseason games, reflecting MLB’s pattern of codifying player protection.
