Came back to roll in grass (8)
I believe the answer is:
returned
'came back' is the definition.
('return' can be a synonym of 'come back')
'roll in grass' is the wordplay.
'roll' becomes 'turn' (turn can mean to roll over).
'in' indicates putting letters inside.
'grass' becomes 'reed' (type of grass plant).
'turn' going within 'reed' is 'RETURNED'.
'to' is the link.
(Other definitions for returned that I've seen before include "Went, came or gave back" , "Sent back" , "dishonoured by the bank" , "Went, came or brought back" , "Came back - voted in" .)
