Cricket post (5)
I believe the answer is:
stump
'cricket post' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for stump that I've seen before include "Small remaining part; cricket item" , "Part of a felled tree that's left in the ground" , "Nonplus" , "Remnant of felled tree" , "Residue after felling" .)
