Run and kick supporter (7)
I believe the answer is:
bootleg
'run' is the definition.
(I've seen this before)
'kick supporter' is the wordplay.
'kick' becomes 'boot' (booting is a kind of kicking).
'supporter' becomes 'leg'.
'boot'+'leg'='BOOTLEG'
'and' is the link.
(Other definitions for bootleg that I've seen before include "Illegally made recordings" , "Type of jeans" , "Run" , "Pirated (copy)" , "Illegal music recording" .)
