Keith Thurman pulled out of his tune-up fight in May meaning that even with a quick turn around, Thurman will have fought twice in three years and would not have fought in almost a year and a half. In my view, this is simply an unacceptable activity level for a unified champion and puts key Welterweight match-ups in limbo. The WBC hasn't called a mandatory defense on the Welterweight title in some time and has recently placed Shawn Porter as the mandatory challenger. The WBA doesn't have a mandatory but Matthysse is the paper titlist. Personally, I think if Thurman can't get in the ring versus a guy like Porter by the end of this year, he should be stripped of his titles. It is unfortunate but I think Thurman's career is going to be wasted because of his injuries. What do you think?
