Former heavyweight champion Tyson Fury will not reapply for a licence to fight.
The Brit had his licence revoked in October last year after allegations of doping emerged.
After hinting at a comeback earlier in the year, Fury tweeted after thinking long and hard about returning, he won't be applying for a license.
The former world champion has not fought since July 2015, when he claimed a series of titles by defeating Wladimir Klitschko in Dusseldorf.
