This is why you don't have female refs, this is not a friggin fight.
If Finney can take it, let her take it. There would be no complaints if a dude was getting mangled for a round and a point taken if he got clubbed in the back of the head half a dozen times. The problem is that Cyborg doesn't have the power, amazingly enough, to actually stop her opponents. Just mangle them up for a while.
