Condition of rugby forward attracting gossip (7)
I believe the answer is:
lockjaw
'condition' is the definition.
(lockjaw is a kind of condition)
'rugby forward attracting gossip' is the wordplay.
'rugby forward' becomes 'lock' (lock is an example).
'attracting' is a charade indicator (letters next to each other).
'gossip' becomes 'jaw' (synonyms).
'lock'+'jaw'='LOCKJAW'
'of' acts as a link.
(Other definitions for lockjaw that I've seen before include "Form of tetanus with rigidly closed mouth" , "Graphic word for tetanus" , "Form of tetanus in which mouth is tightly closed" , "Popular name for tetanus" , "Serious condition" .)
