Endless row — inconclusive result (3)
I believe the answer is:
tie
'inconclusive result' is the definition.
(a sports match with no winner)
'endless row' is the wordplay.
'endless' means to remove the last letter.
'row' becomes 'tier' (tier is a kind of row).
'tier' with its last letter removed is 'TIE'.
(Other definitions for tie that I've seen before include "around the neck?" , "Bind; be equal" , "Neck-cloth" , "Draw - connection" , "It's worn under the collar" .)
