Clear sporting clue is for guys (9)

I believe the answer is:

ridicules

'guys' is the definition.
('ridicule' can be a synonym of 'guy')

'clear sporting clue is' is the wordplay.
'clear' becomes 'rid' (synonyms).
'sporting' is an anagram indicator.
'clue'+'is'='clueis'
'clueis' anagrammed gives 'icules'.
'rid'+'icules'='RIDICULES'

'for' acts as a link.

(Another definition for ridicules that I've seen is " Laughs at".)
