Hurriedly leave game of football and stand round (4,3)
I believe the answer is:
rush out
'hurriedly leave game' is the definition.
I can't tell whether this definition defines the answer.
'of football and stand round' is the wordplay.
'of' becomes 'o''.
'football' becomes 'RU' (rugby union - type of rugby football).
'and' is a charade indicator (letters next to each other).
'stand' becomes 'shut' (I am not sure about this - if you are sure you should believe this answer much more).
'round' means one lot of letters goes inside another.
'ru'+'shut'='rushut'
'o' put within 'rushut' is 'RUSH OUT'.
Can you help me to learn more?
(Another definition for rush out that I've seen is " Charge from defence".)
