Stone slab in battle ground (6)

Ross

I believe the answer is:

tablet

'stone slab' is the definition.
(I've seen this before)

'battle ground' is the wordplay.
'ground' is an anagram indicator ('grind' the letters into a new form).
'battle' with letters rearranged gives 'TABLET'.

'in' is the link.

(Other definitions for tablet that I've seen before include "Prescription" , "Medicine - flat slab - computer" , "Small bar of soap" , "Weekly" , "PC" .)

I've seen this clue in The Sun.
