The career of Wilder is definitely not over but he is 34 years old and even so he still has time to try to get a shot at the title again but it would be better for him to take some time out and fix those issues that he had in his personal life before he went in to the Fury fight. After that he should have two or three warm up fights before trying to set up a title shot against whoever holds the bests and anyway by then he might be the no1 mandatory fighter which would allow him to get another chance at being heavyweight world champion again.
Do you think there will be a third fight between these two? I do not see a re-match but if Wilder get his career back on track maybe he will manage one final shot at the title.
You are talking as if Deontay Wilder ended his career with that match but the truth is careers as good as Wilder don't end like that. Some fighters in the industry like McGregor, Pacquiao, Golovkin didn't let their blemish record define their career and look they still manage to win some games. Yeah a rematch might not be soon to come since that is how hype fight works, promoters will tend to dodge everything for a long time so that they can heat things up for the fans. Fury has the privilege to choose his next match while Wilder will go in a different route to reclaim in order throne and that's how it works for both of them.
