Serious Question: Has a boxer ever crapped themselves during a match before?

It's obviously almost certainly happened among the tens of thousands, hundred of thousands? of fights that happened over the years. Has there been any high profile cases of it happening or potential rumors that it might have happened in a specific fight? A few fighters vomited in between rounds, but I've never seen it in the middle of a round either. What would the procedure for the referee be there? TKO victory? Call time to clean it up? No contest? Go to the scorecards?
