I don't know if this is what you're looking for. Bob Dylan did a song about the death of a boxer inside the ring & no one would except blame. Not the other boxer, the ref, the fans. etcIt's called Who Killed Davey Moore

Who killed Davey Moore, why & what's the reason fro
Not I said the man whose fists laid him into a cloud of mist
Who just arrived from Cuba's door where boxing ain't allowed not more
I hit him, I hit him, yes it's true but that's what I've been paid to do

Don't remember much of the rest, if this is the one maybe others can fill inn the blanks. Good Luck. Barry
