I was looking forward to Thiago Silva vs Lyoto Machida because it was going to answer some questions I really wanted answers to. Now we might not have those answers for a while, because Thiago Silva is out with a back injury. MMAWeekly points out that the UFC has 6 weeks to find a replacement … “plenty of time” in their words. Unfortunately, I doubt there’s going to be anyone with a decent name willing to step up and challenge Machida. No one wants to chase that dude around the cage for 3 rounds and then lose a decision.
