What does “TKO (retirement)” mean on the fighters wiki page

I see this pretty frequently with fighters. They’ll have a TKO retirement loss on their page and then have fights after it. What does that even mean? Do they announce their retirement in the octagon and then come back? Am I stupid? submitted by /u/watz-poppiin [link] [comments]
