History

Historical Context

In August 2013 the NFL settled concussion lawsuits for $765 million, a landmark that spurred other sports to tighten head-injury rules. On October 30 2013 the Boston Red Sox captured the World Series, underscoring MLB’s rising profile. That shift was evident when Diamondbacks manager Torey Lovullo cited league concussion protocols after Ketel Marte’s 93-mph line drive struck Geraldo Perdomo’s helmet in 2024.
