Maybe miss the race after injury (7)
I believe the answer is:
teacher
'maybe miss' is the definition.
(a female teacher might be addressed 'miss')
'the race after injury' is the wordplay.
'after injury' indicates anagramming the letters.
'the'+'race'='therace'
'therace' is an anagram of 'TEACHER'.
(Other definitions for teacher that I've seen before include "'Instructor, educator (7)'" , "Guide" , "Member of school staff" , "CARRY ON FILM" , "One who educates" .)
