As much as I rate Kostya, he really should stay retired. One more fight proves nothing. He has been out for a long time since Hatton and before that had fought only once in a very, very long time...

He is in his late 30's and has fought a handful of fights in 5 years...If he was to come back it should have been sooner, now he should just bow out...

He has his pride still intact, no need to take any more risks....
