After first of fumbles, shocking goalie leaves (7)
I believe the answer is:
foliage
'leaves' is the definition.
(I've seen this before)
'after first of fumbles shocking goalie' is the wordplay.
'after' is a charade indicator (letters next to each other).
'first of fumbles' becomes 'f' (1st letter of 'fumbles').
'shocking' indicates anagramming the letters (I've seen this in other clues).
'goalie' with letters rearranged gives 'oliage'.
'f'+'oliage' is 'FOLIAGE'.
(Other definitions for foliage that I've seen before include "Green leaves" , "(Decorative) leaves" , "Greenery, leaves of trees or plants" , "Mass of leaves" , "Leaves of tree or plant" .)
