The most possible route for AJ as f now. He will definitely fight either Price or Molina in December. Probably Price as Molina is unknown in Great Britain, and Price also claims he KO'd AJ 5 years ago in sparring. Then IBF orders him to fight Pulev, who becomes official challenger after Parker goes for vacant WBO title. After that AJ most likely faces Whyte if Dillian beats shot Dereck Chisora this fall. And only after that we will see AJ vs other champions or former champions.
As of now thats only rumor, but Hearn never denied possible Price fight when asked in Twitter. Pulev is ready, but only in the next year as he said, and IBF has strict rules so AJ has to face official challenger next. And Whyte is logical step, Whyte isnt world class, so it makes sence for Hearn to make their 2nd fight before Whyte loses to anybody else and becomes irrelevant.
Pulev is the biggest fight he can get at the moment if he wants a bit of a test. The other picks are just stay busy fights, with no elements of surprise to them.
