Flinch seeing husband run and fall going round defender (6,4)
I believe the answer is:
shrink back
'flinch seeing husband run' is the definition.
'shrink back' can be an answer for 'flinch' (shrinking back is a kind of flinching). I am not certain of the 'seeing husband run' bit.
'fall going round defender' is the wordplay.
I cannot quite understand how this works, but
'fall' could be 'shrink' (shrinking is a kind of falling) and 'shrink' is found within the answer.
'defender' could be 'back' (I've seen this before) and 'back' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'and' acts as a link.
(Another definition for shrink back that I've seen is " Recoil".)
