Fat-headed rugby player in a group (5)
I believe the answer is:
flock
'a group' is the definition.
The answer is an example.
'fat-headed rugby player' is the wordplay.
'fat-headed' becomes 'f' (this might be a standard abbreviation which I don't know about).
'rugby player' becomes 'lock' (position in rugby).
'f'+'lock'='FLOCK'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for flock that I've seen before include "Raised-pattern (wallpaper)" , "A company of sheep" , "A number of sheep" , "Bevy" , "Congregation" .)
