Athletic team's out-of-date meat (6)
I believe the answer is:
oldham
'athletic team's' is the definition.
(Oldham Athletic is a football team)
'out-of-date meat' is the wordplay.
'out-of-date' becomes 'old'.
'meat' becomes 'ham' (ham is a kind of meat).
'old'+'ham'='OLDHAM'
(Other definitions for oldham that I've seen before include "Town NE of Manchester, Churchill once its MP" , "Town north-east of Manchester" , "Town near Manchester" , "Pennine town in Greater Manchester" , "Northern town" .)
