Abandon a bit of boxing for a bit of footie (9)
I believe the answer is:
kickabout
'abandon a bit of boxing for a bit of footie' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'abandon a bit of boxing for a bit of footie' is the wordplay.
'a bit of' indicates taking the first letters.
'boxing' becomes 'bout' (bout is a kind of boxing).
'for' says to put letters next to each other (I've seen this in other clues).
'a bit of footie' becomes 'kick' (I can't justify this - if you can you should give a lot more credence to this answer).
The first letter of 'abandon' is 'a'.
'a'+'bout'='about'
'about' after 'kick' is 'KICKABOUT'.
Can you help me to learn more?
