The context of your question seems to be related to the recent passing of Sir Mo (real name Bobby Horne) of the former WWE tag team Men on a Mission, and the actions of AEW President Tony Khan.
Based on the information available:
Sir Mo passed away recently at age 58 after battling serious health complications, including a severe blood infection and pneumonia, following years of health issues like a kidney transplant and COVID-19.
Tony Khan is the owner, CEO, and head booker of All Elite Wrestling (AEW).
There is no known public incident or scenario where Tony Khan would have been in a position to "save" Sir Mo from his medical conditions or death. Sir Mo had been dealing with a series of long-term and acute health issues, and there's nothing to suggest Khan was personally involved in his medical care or had a chance to intervene in a life-or-death situation.
The phrasing of the question may be based on a misunderstanding or an unverified rumor about a past incident, but the search results do not indicate any such event.
