Nathan Cleverly will fight for the WBO light-heavyweight title next.
That's because the WBO have ordered that negotiations should begin between Cleverly's camp and that of German champion Jurgen Braehmer.
Braehmer was due to meet WBA champion Beibut Shumenov earlier this month, but missed the fight through illness.
That appeared to be a blow for Cleverly. It was feared he would have to wait until the outcome of a rearranged fight between Braehmer and Shumenov before getting his chance.
But now if Braehmer decides to fight the Kazak, he will be stripped, and Cleverly will challenge for the vacant title.
Braehmer's other option is to defend against Cleverly.
Warren tried to bring Braehmer to the UK in December to meet Cleverly in Liverpool.
And he will be confident he can tempt the 32-year-old to Britain, possibly in March.
