Ripped: topless professional fighter in ring (6)
I believe the answer is:
torero
'fighter in ring' is the definition.
(bullfighter)
'ripped topless professional' is the wordplay.
'ripped' becomes 'tore' (I've seen this in another clue).
'topless' means to remove the first letter.
'professional' becomes 'pro' (abbreviation).
'pro' with its initial letter taken off is 'ro'.
'tore'+'ro'='TORERO'
(Other definitions for torero that I've seen before include "Spaniard in ring" , "Bullfighter" , "Escamillo, for example" , "hero in the ring" , "One perhaps impaled" .)
