Drained Tyson Fury got up on the throne (7)
I believe the answer is:
regnant
'on the throne' is the definition.
(I've seen this before)
'drained tyson fury got up' is the wordplay.
'drained' says to hollow out the word (remove centre letters).
'fury' becomes 'anger' (fury is intense anger).
'got up' shows that the letters should be reversed in order.
'tyson' with its centre removed is 'tn'.
'tn'+'anger'='tnanger'
'tnanger' reversed gives 'REGNANT'.
(Other definitions for regnant that I've seen before include "Ruling" , "Current" , "Reigning" , "On the throne" , "(Queen) in her own right" .)
