Rushed violently into harm, left extremely exhausted (7)
I believe the answer is:
hurtled
'rushed violently' is the definition.
(I've seen this in another clue)
'harm left extremely exhausted' is the wordplay.
'harm' becomes 'hurt' (synonyms).
'left' becomes 'l' (common abbreviation).
'extremely' says to hollow out the word (remove centre letters) (only the extremes of the word are used).
'exhausted' with its centre removed is 'ed'.
'hurt'+'l'+'ed'='HURTLED'
'into' acts as a link.
(Other definitions for hurtled that I've seen before include "shot" , "Crashed" .)
