Deal with placing second after field event (7)
I believe the answer is:
discuss
'deal with' is the definition.
(discussing is a kind of dealing with)
'second after field event' is the wordplay.
'second' becomes 's' (common abbreviation).
'after' means one lot of letters go next to another.
'field event' becomes 'discus' (discus is a kind of field event).
's' put after 'discus' is 'DISCUSS'.
'placing' is the link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for discuss that I've seen before include "Debate" , "Consider" , "Talk about (something)" , "Go into" , "Argue" .)
