Denials involved seal furs (8)
I believe the answer is:
Here is my best explanation:
'denials' is the definition.
(refusal is a kind of denial)
'involved seal furs' is the wordplay.
'involved' indicates an anagram.
'sealfurs' is an anagram of 'REFUSALS'.
(Other definitions for refusals that I've seen before include "problems for showjumpers?", "negative decisions" and "Denials".)
