Canelo Alvarez has been removed from the new World Boxing Council ratings for May as the Mexican serves out a six-month ban handed down by the Nevada State Athletic Commission.
The two-weight world champion lost out on a lucrative rematch with WBC middleweight champion Gennady Golovkin on May 5 after testing positive for Clenbuterol on two occasions.
Canelo has the full backing of the WBC and will be reinstated to the list once his suspension is served.
WBC President Mauricio Sulaiman is hopeful the fight could happen again in September, although Gary 'Spike' O'Sullivan could be the perfect stop-gap for Canelo before facing Golovkin again in May 2019.
Jason Quigley is a big mover as the Irishman heads up to number three, whilst Daniel Jacobs holds the top spot with Demetrius Andrade at two.
O'Sullivan is currently rated eighth ahead of Jack Culcay and rival Yamaguchi Falcao.
