Does a doctor stoppage from an accidental eye poke count as a TKO for a RIZIN winning-method prop?

Short answer

Not automatically. “Doctor stoppage” describes why action stopped; it does not, on its own, establish a TKO for betting. An accidental-foul stoppage needs the official RIZIN result and the rules applicable to that bout. Match the announced result to the operator’s method-of-victory definitions instead of assuming all doctor stoppages count as TKOs.

Official RIZIN rules; use the announced bout result for its method classification
