Hadn't seen that in ages or from that angle, really did look like a nut shot so that's just a poor call. But it's still an individual foul, if a much worse one than Wlads. It was the rate at which Wlad held, leaned on or pushed Povetkin which made it so shit, the ref never took any control of what became an excuse for a fight. Guys do a lot worse things now and then, but I've never seen a boxer so repeatedly foul in a championship fight. Of course as you love to point out nothing was being called, but I still can't help blame Wlad for stinking it out when he didn't have to. He could have easily KO'ed Povetkin imo, if he just bothered to actually put anything together or jab more instead of initiating that crap.
