Historical worker tending horses stabled at an inn (6)

I believe the answer is:

ostler

(Other definitions for ostler that I've seen before include "Horse man" , "ER lost (anag) - former stableman" , "Stableman at old coaching inn" , "Groom, stableman" , "One taking care of horses at an inn" .)

I've seen this clue in The Times.
