Set up bank, receiving warning over mostly bad grounds for dismissal (3,6,6)

Ross

I believe the answer is:

leg before wicket

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

'dismissal' is the definition.
(I know that leg before wicket is a type of dismissal)

'set up bank receiving warning over mostly bad grounds' is the wordplay.
I cannot really understand how this works, but
'warning' could be 'fore' (shouted in golf) and 'fore' is found in the answer.
This explanation may well be incorrect...

'for' is the link.

Can you help me to learn more?

(Another definition for leg before wicket that I've seen is " Way to get out".)

I've seen this clue in The Times.
