Supposedly from "unknown causes" but there is speculation that it was from the Mrna covid vaccine, his wife denies it, and it can never be proved if one dies from the vaccines. And the data is released daily on the deaths from the Mrna vaccines.

Well, looks like it was a cover up on Marvin's death.


Boxing Champ Dies After Vaccine; Media Scramble to Cover It Up
March 15, 2021
The death of boxing champ Marvin Hagler, 66, has stirred up a firestorm of controversy over his cause of death.

March 13, 2021, Hagler’s friend and rival, boxer Thomas “Hitman” Hearns, posted on his Instagram and Twitter accounts that Hagler was in the hospital ICU “fighting the after effects of the vaccine” and that he wanted fans to pray for Hagler.

Later in the day, Hagler’s wife, Kay, posted on Hagler’s Facebook fan page that he’d passed away “unexpectedly.” She didn’t mention his cause of death.

However, Hearns’ statement about Hagler having serious side effects from the COVID vaccine spread quickly over the internet, while major media worked to quell or completely ignore the idea that he might have died from the vaccine.

The New York Times, for example, simply didn’t mention it. Fox News did talk about it, and repeated Hearns’ comments about the hospital stay, adding that “Hearns’ post had “sparked anti-vaccine messages on social media.” The Sun took it a step further, saying anti-vaxxers were using Hagler’s death to push their agenda.

Hearns also followed up with a clarification that he “wasn’t trying to make an anti-vaccine message” — but didn’t retract his earlier statement about Hagler’s ICU stay or the vaccine reaction.

“Marvelous” Marvin Hagler’s sudden death over the weekend had nothing to do with the COVID-19 vaccine, the wife of the late boxing legend clarified.

Kay Hagler slapped down speculation that Hagler, 66, died after receiving the jab.

“I do NOT accept to read some stupid comment without knowing really what happen,” she wrote in a post on the Marvelous Marvin Hagler Fan Club page on Facebook. “For sure wasn’t the vaccine that caused his death. My baby left in peace with his usually smile and now is not the time to talk nonsense.”

On that same page, Kay revealed that her husband of 21 years — one of the great middleweights in boxing history — passed away unexpectedly at his New Hampshire home.

Following the news, an Instagram post by one-time rival-turned-pal Thomas Hearns fueled rumors of what caused the Newark, NJ-born boxer’s death.

“A real true warrior Pray for the king and his family.. he’s 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!” Hearns wrote in the since-deleted post, according to Boxing Insider.

Hagler’s own website says he died of “natural causes near his home in New Hampshire” but does not elaborate.

Although I no longer follow the sport because it is so corrupt, I was a big boxing fan and saw Hagler fight in person several times.
