His son Adam confirmed the tragic news in an email on Thursday in the United States.

"It is with the deepest sadness that I tell everyone that early this morning, Jimmy Glenn, my father, passed away," his youngest son, Adam, wrote.

The popular and well known figure was a former amateur boxer himself and once trained legendary heavyweight, Muhammad Ali.

Glenn also owned a famous Manhattan bar near Times Square called 'Jimmy's Corner' that has been a New York institution for decades.

The bar is littered with boxing memorabilia on its walls and has been a hot spot for locals and tourists alike for more than 40 years.

Upon news of his death, tributes have been pouring in on social media.

Glenn's son Adam told ABC News that he and his father both contracted coronavirus a month ago but his dad's pre-existing medical condition stymied his recovery.

He was admitted to a New York hospital two weeks ago and family members learnt that Glenn was set to receive a convalescent plasma treatment imminently, after other medicals failed to work.

"His condition rapidly worsened overnight, and finally his body just did not have the strength to continue fighting," Adam Glenn wrote.

Glenn is survived by seven children, nine grandchildren and four great grandchildren.

He was inducted into the New Jersey Boxing Hall of Fame in 2002.
