evidence: The wife of boxing legend "Marvelous" Marvin Hagler says he died peacefully at the New Hampshire home they shared together, rejecting rumors circulating that the COVID-19 vaccine caused his death. [...] Hagler, one of the all-time greatest middleweight fighters, died Saturday (March 13) at age 66. The cause of death has not yet been publicized. According to Boxing Insider, just before he passed away, his former boxing rival and eventual friend Thomas Hearns posted a since-deleted note to social media saying that the boxer was "in ICU fighting the after effects of the vaccine! He’ll be just fine but we could use the positive energy and Prayer for his Full Recovery!" That post reportedly led to unsubstantiated rumors that Hagler’s death was a result of taking the COVID-19 vaccine. [...] He is not the first sports legend to have false rumors swirl about the COVID-19 vaccine causing his death. Baseball icon Hank Aaron, who died Jan. 22, was also rumored to have succumbed to the effects of the vaccine. But both Morehouse School of Medicine, the Atlanta Braves and Atlanta Mayor Keisha Lance Bottoms quickly shot down that gossip. "His passing was not related to the vaccine, nor did he experience any side effects from the immunization," Morehouse said in a statement given to WSB-TV.
