I believe the answer is:

oldham

I'm a little stuck... Click here to teach me more about this clue!

'athletic' is the definition.
(I know that athletic can be written as Oldham)

'veteran actor' is the wordplay.
'veteran' becomes 'old' (I've seen this in another clue).
'actor' becomes 'ham' (ham is a kind of actor).
'old'+'ham'='OLDHAM'

'corny but possibly' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.

Can you help me to learn more?
