Carrying out transfer of a second new player? (9)

I believe the answer is:

assigning

'carrying out transfer' is the definition.
(assigning someone to a new place)

'a second new player?' is the wordplay.
'second' becomes 's' (common abbreviation).
'new player?' becomes 'signing' (eg a new signing for a football team).
'a'+'s'+'signing'='ASSIGNING'

'of' acts as a link.

I've seen this clue in The Guardian.
