Pulled out of race, slightly injured (9)
I believe the answer is:
scratched
I believe this clue is a double definition.
'pulled out of race' is the first definition.
(scratch can mean to withdraw from a race)
'slightly injured' is the second definition.
(a scratch is a minor injury)
(Other definitions for scratched that I've seen before include "Relieved an itch" , "injured" , "struck out" , "Having surface damage" , "Pulled out of contest" .)
