Group of players not finishing meal (3)
I believe the answer is:
tea
'meal' is the definition.
(tea is a type of meal)
'group of players not finishing' is the wordplay.
'group of players' becomes 'team' (I've seen this before).
'not finishing' means to remove the last letter.
'team' with its last letter removed is 'TEA'.
(Other definitions for tea that I've seen before include "brewer's product" , "Hot infusion" , "Brew" , "Perhaps Indian" , "Popular beverage brewed at home" .)
