Per Pugmire.
A Tuesday morning conference call is scheduled among Sulaiman, IBF President Daryl Peoples and World Boxing Assn. head Gilberto Mendoza to discuss Golovkin's next bout.
....
But Sulaiman says he will inform his peers that his organization has already determined Charlo will be ordered as the mandatory foe for Golovkin after the champion fights Alvarez later this year, or if he declines to fight Alvarez following their September draw in Las Vegas.
....
DiBella says IBF rules seem to mandate a Golovkin fight against Derevyanchenko now that the champion is selecting a "discretionary fight" while awaiting how the Nevada Athletic Commission will discipline Mexico's former two-division champion Alvarez.

Derevyanchenko then er what?
DiBella is making a very strong case for Derevyachenko.
"When a guy is sitting in a mandatory spot, he's not getting paid until he gets that fight. And if Golovkin faces Canelo next, this decision could affect for 18 months."
WBC have already written Charlo off and he'll have to wait until after the Canelo fight in September.
