Katie Taylor has been named 'Champion in Recess' by the WBC, having informed the sanctioning body she plans to take some time away from the sport.
The undisputed light-welterweight champion won her trilogy fight with Amanda Serrano in New York on 11 July.
The WBC then announced she would have to face mandatory challenger Chantelle Cameron in a title defence, in what would be the third leg of another trilogy.
However, after informing the body she plans to take some time away "to attend to personal matters", Taylor has now been recognised as its emeritus champion, with Cameron now set to face Sandy Ryan in an all-English fight for the vacant belt.
Should Taylor opt to return to the ring in the future, the 39-year-old would be first in line to challenge to holder because of the status conferred on her.
"She let us know that she plans to take some time away from the ring to attend to personal matters," said WBC president Mauricio Sulaimán.
"The fight she was obligated to take was against Chantelle Cameron; by naming her Champion in Recess, we will order Sandy Ryan to fight Cameron to ratify the WBC super lightweight world title."
