Brock Lesnar Stripped Of IWGP Title, MMA Future, Reasons Behind 'No Show', More

PuroresuPower.com reports that "due to problems with a work visa, Brock Lesnar will not face Hiroshi Tanahashi for the IWGP title on the promotion's 7/17 Sapporo (Tsukisamu Green Dome) show. The promotion is offering refunds to fans with tickets for the show."
As Zach Arnold npted on the Puroresu website, Lesnar not appearing could be due to his decision to perform in Mixed Martial Arts. Dave Meltzer reports that Lesnar had a huge falling out with the promotion. The rumor is that it was due to Lesnar not wanting to drop the title as it would diminish his credibility. This pertains to his upcoming career in MMA.
If this is true, I can't understand how Lesnar could think dropping the title in a match would diminish his credibility in MMA.
And why do I say that? Think about it. You can have all the credibility in the world. But if he gets his ass kicked in a MMA match, credibility of not losing the IWGP belt in a match means shi*.
