'an early rugby league star' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'hang about with courier' is the wordplay.
'hang about' becomes 'dally' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'with' is a charade indicator (letters next to each other).
'courier' becomes 'messenger' (synonyms).
'dally'+'messenger'='DALLY MESSENGER'
