Record held by player, e.g., is terrific (8)
I believe the answer is:
register
'record' is the definition.
(register is a kind of record)
'held by player e g is terrific' is the wordplay.
'held by' indicates a hidden word.
'REGISTER' is hidden in the letters of 'player e g is terrific'.
(Other definitions for register that I've seen before include "Written record of names, etc" , "Index" , "Vocal compass" , "Greet sir (anag.)" , "Official record of names, transactions" .)
