Came in (7)
I believe the answer is:
entered
'came in' is the definition.
('enter' can be a synonym of 'come in')
This is all the clue.
(Other definitions for entered that I've seen before include "Ten deer (anag) - went in" , "Put down" , "Came in; recorded" , "Enrolled or went in" , "Logged; arrived" .)
