Team-beater’s hairy facial growth (4,8)

I believe the answer is:

side whiskers

'hairy facial growth' is the definition.
(style of facial hair)

'team-beater's' is the wordplay.
'team' becomes 'side' (both can mean a sports team).
'beater's' becomes 'whisker's' (something for beating or whisking food).
'side'+'whiskers'='SIDE-WHISKERS'
