Kickoff prop (3)
I believe the answer is:
tee
'kickoff prop' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for tee that I've seen before include "A golfer hits from here" , "Golfing support" , "Golf peg" , "'Drive off it, half-laughing (3)'" , "Golfing item" .)
