I don't know why so many people are pretending to struggle to understand the difference between normal interim titles which feature the existing challenger staying in to fight the champ's injury replacement, thus determining the new contender given the existing contender is putting his status on the line.
And this one here where Pav replaced Jones, the injured champion, and then the UFC randomly decided he should fight Aspinall instead of Stipe, the existing challenger, as had literally already been agreed upon.
Stipe never lost to Aspinall. Pav did. Why should Stipe lose his title shot for Pav's loss?
