The rest of the players could make them fail (4-4)
I believe the answer is:
half-time
'the rest of the players' is the definition.
(rest period for sports players)
'make them fail' is the wordplay.
'make' is an anagram indicator.
'them'+'fail'='themfail'
'themfail' anagrammed gives 'HALF-TIME'.
'could' acts as a link.
(Other definitions for half-time that I've seen before include "Pause in middle of game" , "Interval at games" .)
