Those playing rugby leap, but only the backs land (5)
I believe the answer is:
egypt
'land' is the definition.
(Egypt is an example)
'those playing rugby leap but only the backs' is the wordplay.
'only the backs' suggests the final letters (only the letters at the back are used).
The final letters of 'those playing rugby leap but' are 'EGYPT'.
(Other definitions for egypt that I've seen before include "North African nation" , "Part of Africa" , "Cairo is its capital" , "North African state" , "Cleopatra's country" .)
