Not over, but his title chances almost gone. He could get through a couple of years fighting some domestic fights like Price, Dubois, Joyce, Chisora 3, as well as fights like Parker 2 would be options for him.
I wouldn't say his career is over, but he will have found his level. He was expecting to roll over an old, shot Alexander Povetkin. If he can't do that, then where does he go? Maybe fight the likes of Daniel Dubois and Filip Hrgovic, he could make an entertaining gatekeeper.
