In October 2014, the "Portland Tribune" reported that Haynes filed a lawsuit in federal court against WWE, alleging "egregious mistreatment of its wrestlers for its own benefit, as well as its concealment and denial of medical research and evidence concerning traumatic brain injuries suffered by WWE wrestlers." This litigation was taken after research into chronic traumatic encephalopathy (CTE), which was attributed to causing the deaths of Chris Benoit in 2007 and Andrew Martin in 2009. Haynes also sought for the court to grant class action status for hundreds of former wrestlers and to force WWE to establish a medical trust fund to pay for wrestlers who suffer from injuries that took place in a WWE ring. Former WWE stars Vito Lograsso and Adam Mercer filed a class action lawsuit against WWE in January 2015 while being represented by the same lawyer as Haynes, Konstantine Kyros. In March 2016, the suit was dismissed by Judge Vanessa Lynne Bryant. At the time of dismissal, dozens of former WWE wrestlers had joined a class action lawsuit under Kyros's counsel. On July 8, 2019, Kyros and the wrestlers (now totaling 67 wrestlers and estates of deceased wrestlers) filed their latest appeal in the class-action lawsuit known as "Haynes, Laurinatis, et. al., v. World Wrestling Entertainment, Inc., et. al.".
