I'm not sure if you're fishing Malice. if you are; nice, you'll pull in plenty with that bait
If you're not, then you have to weigh up the benefit of this alleged 'ruse' versus the loss to the UFC of having one of their biggest drawcards not fighting on one of the most anticipated cards this year.
Surely, if Lesnar is fit and healty as you suspect, the UFC could have come up with some sort of publicity stunt that
didn't involve him having to vacate the title and instituting an interim one in its place?
Personally, I would have gone for:
'UFC Heavyweight champ Brock Lesnar attacked by Sasquatch in Minnesota backwoods! Lesnar: "That hairy bastard couldn't handle my ground'n'pound!"' more info to follow, etc, etc, etc...
Sorry Malice, for me, the cost-benefit analysis doesn't add up
