-- Chael Sonnen recently claimed in an interview that CM Punk would be in Boston on Saturday for UFC Fight Night 26, where Sonnen will face Shogun Rua in the main event, and then the two would head to SummerSlam together. However, he will not be there as the previously-announced SummerSlam AXXESS schedule for Saturday has Punk at an event from 6 PM though 8 PM, which is the same time as the UFC show. It all depends on if CM Punk is able to get out of his AXXESS appearance for UFC and that's highly unlikely.
