loss by.........tko ......injury retirement (RTD) it depends on the governing body over seeing the event
how the loss is worded.
Personally I prefer the RTD when it comes to a legit injury stoppage, a tko should benefit the opponents particaption and a tko loss does punish the losers time span to be able to return to the ring. Again the "body" (federation, state, region, country etc..)over seeing the event will have presidence as to time duration banning. Most times a tko will be 30 to 60 days and a KO will be 90 to 120 days.
